Free Flowmeter Rental Program
Nitrogen and Compressed-Air Flowmeter Rental
One of the biggest mysteries in this industry is how much nitrogen do I actually use. Borrow a flowmeter, measure your real flow for a week or two, and use the data to size an on-site generator that pays you back. Free of charge across the United States, Mexico, and Canada.
No rental fee, no deposit, no purchase pressure
Live web dashboard, no WiFi required
Pipe size range, point of use to plant supply
High-pressure variant available
Measure First, Then Size
How much nitrogen do you actually use?
Most facilities cannot answer that question accurately, and the answer matters. Sizing an on-site nitrogen generator off equipment nameplate flow tends to over-size the system, which raises the capital cost and the kilowatt-hour bill without producing more usable gas. Sizing off measured flow lands the generator at the right capacity, the right purity tier, and the right compressor pairing. The flowmeter rental program exists so any customer can measure first and decide later, with no fee and no commitment.
The fleet covers four use cases. Most customers want a rental kit with a digital meter and a cellular data logger that captures average flow, peak events, and duty cycle on the main supply line. Some want point-of-use measurement on a single laser, soldering machine, or packaging line so they can size the generator branch by branch. Fiber laser and other high-pressure work needs the high-pressure variant rated up to 600 PSIG. Engineering teams who want to dig into meter physics, units, and install positions can read the technical reference. Pick the path that fits your shop and we will send the right kit.
The rental is free of charge. Outbound shipping is on us, and the customer covers return shipping at the end of the window on any standard carrier account. Standard term is 30 days, longer on request. The whole point is to remove every reason not to measure before sizing.
Rental Hardware
What the rental kit looks like in the field
The same digital flowmeter and cellular data logger ships across the four pathways, sized to the install point. The kit clamps onto an existing nitrogen line, captures real flow under production load, and streams the data to a web dashboard you can open from any phone or computer.
Four Pathways
Pick the kit that fits your measurement
Each path uses the same free rental program with the same cellular data logger. The kit shape changes based on where you are measuring, what pressure you are running, and how deep you want to go.
Pathway 1 / Most common
Rental kits with cellular data loggers
The standard kit. Digital flowmeter plus cellular data logger sized for your existing nitrogen or compressed-air supply line. Captures average flow, peak events, and full duty-cycle profile across a 30-day window. The first move when you are sizing a facility-level on-site generator.
View rental kits →Pathway 2 / Per-machine sizing
Point-of-use measurement
A small inline meter installed at a single piece of equipment so you can see exactly what that one machine consumes. Used for fiber laser cutters, selective and reflow soldering machines, MAP packaging lines, electronics inerting cabinets, and any single tool that drives the bulk of your nitrogen demand.
See point-of-use details below →Pathway 3 / High pressure
High-pressure flowmeter rental
Fiber laser cutting and other high-pressure assist gas applications run well above the rating of a standard meter. The high-pressure rental kit is rated for up to 600 PSIG and pairs with the same cellular data logger. The sizing math from the rental drops directly into a high-pressure on-site generator quote.
View HP flowmeter →Pathway 4 / Engineering reference
Flowmeter technical reference
For engineering teams who want the meter physics, the unit conversions between SCFM, SCFH, and Nm3/h, the install-position rules, and the data logger architecture explained in detail. The reference page also covers what each meter type cannot do, which matters when you are picking the right tool for the measurement.
Read the technical reference →Point of Use
Measure a single machine instead of the whole plant
A facility-level meter answers what does the plant consume. A point-of-use meter answers what does this one machine consume. The point-of-use measurement matters when one piece of equipment drives most of your nitrogen demand and you want to size the on-site generator branch by branch instead of from a single plant-wide number. The same free rental program covers point-of-use measurement with a smaller meter sized for the branch line at the equipment.
Common point-of-use applications
Fiber laser cutters
Assist-gas demand varies with sheet thickness, nozzle, and cutting speed. A meter installed on the laser drop captures the real per-cutter consumption profile and lets you size a generator that matches one laser, two lasers, or a shared header for a multi-laser shop. High-pressure laser duty uses the high-pressure rental kit instead.
Selective and reflow soldering machines
Per-machine flow on selective solderers and reflow ovens varies with hood configuration, conveyor speed, and the number of zones being inerted. A point-of-use meter on the supply drop captures real flow under production load instead of the worst-case nameplate, which is usually higher than what the line actually pulls.
MAP and packaging lines
Modified-atmosphere packaging on snack, dairy, salad, and protein lines pulls nitrogen at the filler, the conveyor purge, and any blanketing point. Measuring at the line drop instead of plant-wide separates real packaging demand from other facility uses. Critical when you are sizing for a single product line versus a multi-line plant.
Electronics inerting cabinets and glove boxes
Inerting cabinets, dry boxes, and analytical glove boxes draw small but continuous nitrogen flows. Point-of-use measurement gives you the exact daily volume per cabinet, which lets you choose between a small dedicated lab generator and a tap off the existing facility supply.
Why point-of-use matters for sizing
A plant-level reading averages every machine and every shift together. That average is fine for a single-product, single-line facility. It is misleading the moment one piece of equipment drives the demand or the shop runs mixed product lines that consume nitrogen at different rates. Point-of-use measurement breaks the load down by source, which lets the on-site generator be sized to actual peak demand at the bottleneck rather than to a smoothed plant average.
The other use case is hidden waste. Many shops discover they have a leak, a regulator left open, or an idle drop bleeding gas continuously. A point-of-use meter exposes that pattern within the first 24 hours of the rental. Fixing the leak before the generator quote is finalized often shifts the recommendation down a size class, which lowers the capital number and the kilowatt-hour bill.
How It Works
Four steps from request to sized data file
Step 01
Tell us your line
Send four numbers: the application you are measuring, the existing pipe size at the install point, an estimate of expected flow, and the operating pressure. Rough numbers are fine. We use them to pick the right meter size and pressure rating from the fleet.
Step 02
We ship the kit at no cost
The kit goes out with the meter, the cellular data logger, install fittings, and a one-page setup sheet. Outbound shipping is free across the United States, Mexico, and Canada. The customer covers return shipping at the end of the rental on their own carrier account.
Step 03
Install and measure
Drop the meter inline on the supply line at the position we recommend. Power the cellular data logger from the included supply. The logger streams readings to our servers in real time over its built-in cellular link, with no WiFi setup and no IT involvement. Standard measurement window is 30 days, longer on request.
Step 04
View the live trace, ship the kit back
View the live flow trace on a web dashboard from any phone, tablet, or computer throughout the rental. At the end of the window, ship the kit back. The data is already yours because the logger has been streaming the entire time. We follow up with a summary of average flow, peak flow, and duty cycle, and the data drops directly into a generator quote when you are ready.
Purchase Option
Want to own a meter for ongoing audits?
Most customers measure once during sizing and ship the rental kit back. Some prefer to own a meter outright so they can run periodic flow audits as production changes, equipment is added, or new product lines come online. The same digital flowmeters in the rental fleet are available for outright purchase across the full pipe-size range and including the high-pressure variant.
Pricing depends on size, pressure rating, and which data-logger options you want. Tell us what you are measuring and we will send a quote.

Flowmeter rental program
What is the difference between this page and the rental kits page?
This page is the umbrella for the whole flowmeter program. It routes you to the right kit based on what you are measuring. The rental kits page is the most common path: a digital flowmeter and cellular data logger sized for the main supply line at a facility. The point-of-use section on this page covers per-machine measurement at a single piece of equipment. The high-pressure page covers fiber laser and other applications above standard meter rating. The technical reference page covers meter physics and unit conversions for engineering teams. All paths use the same free rental program.
Is the rental really free of charge?
Yes. No rental fee, no deposit, no purchase pressure. We send the kit at no cost. The customer covers return shipping at the end of the rental on a standard ground carrier account. The reason the program exists is that right-sizing a generator off measured flow is much more accurate than sizing off nameplate, and the customer who measures first ends up with a better-fit system. We would rather help you measure than guess.
How do you decide which kit to send?
Send four numbers: the application you are measuring, the existing pipe size at the install point, an estimate of expected flow, and the operating pressure. With those four numbers we pick the right meter size, the right pressure rating, and the right data-logger configuration from the fleet. If the answer is point-of-use at a single machine, we send a smaller meter sized for the branch line. If the answer is plant-level, we send a larger meter for the main supply.
When do I want point-of-use measurement instead of a plant-level reading?
When one piece of equipment drives most of your nitrogen demand, when you run mixed product lines that consume nitrogen at different rates, or when you suspect a leak or open regulator. Point-of-use measurement breaks the load down by source so the on-site generator can be sized to the actual peak demand at the bottleneck rather than to a smoothed plant average. Common point-of-use applications include fiber laser cutters, selective and reflow soldering machines, MAP packaging lines, and electronics inerting cabinets.
Do you sell the meters as well as rent them?
Yes. The same digital flowmeters in the rental fleet are available for outright purchase across the full pipe-size range and including the high-pressure variant. Most customers measure once during sizing and ship the rental kit back. Some prefer to own a meter for ongoing audits as production changes or new lines come online. Pricing depends on size, pressure rating, and data-logger options. Tell us what you are measuring and we will send a quote.
What pressure can the meters handle?
The standard rental kit covers typical compressed-air and nitrogen-supply pressures. The high-pressure variant is rated for up to 600 PSIG and is built for fiber laser cutting and other high-pressure applications. The high-pressure rental is a separate kit with its own page. Tell us your operating pressure and we will pick the right kit from the fleet.
How does the cellular data logger work?
The cellular data logger pairs with the digital flowmeter and streams readings to GGS servers over a built-in cellular link. There is no WiFi setup, no IT involvement, and no on-site network access required. You can view the live trace on any phone, tablet, or computer through a web dashboard throughout the rental. The logger captures average flow, peak events, and a full time-stamped trace. At the end of the rental we send a summary alongside the raw trace from the dashboard.
Where do you ship?
Outbound shipping is free across the United States, Mexico, and Canada. The customer covers return shipping at the end of the rental on their own carrier account. If you are outside that geography, ask and we will see what the program looks like for the specific location.
Send four numbers and we will pick the right kit
The application you are measuring (laser cutting, soldering oven, MAP packaging line, heat treating, glove box, or other), the existing pipe size at the measurement point, an estimate of expected flow, and the operating pressure. With those four numbers we send the kit at no cost.
