Flowmeters

Check the flow rate of liquids in your system. As your liquid flows through these flowmeters, it pushes an indicator up the scale, showing you the flow rate. Mount them vertically inline with your piping system, so liquid flows up from the bottom. They’re made from acrylic, so they’re completely clear to help you inspect your liquid’s color and clarity for any problems. They also have a white backing to help you read the scale clearly.

These flowmeters are calibrated with water but can be used with other liquids except for oil. If you’re using these with a liquid other than water, you’ll need to calculate the flow rate by multiplying the number shown on the scale by the specific-gravity conversion factor for your liquid.

Choose a fitting material that is compatible with the liquid you're running through your line.

Polypropylene Fitting—Polypropylene fittings work with a wide range of chemicals. However, they can crack from impact or when overtightened.

PVC Fitting—PVC fittings work with a wide range of chemicals. However, they can crack from impact or when overtightened.

Brass Fitting—Brass fittings resist impact better than polypropylene and PVC fittings.

316 Stainless Steel Fitting—316 stainless steel fittings resist impact better than polypropylene and PVC fittings.

Calibration Certificate Traceable to NIST—Flowmeters with a calibration certificate traceable to NIST states that the flowmeter has passed a test for accuracy.

Rectangular Body


Female	Male	Replacement Straights	Replacement Flowmeter Repair Kits

Flowmeters with a rectangular body are made from a single block of acrylic, so they’re more durable and resist impact better than flowmeters with a cylindrical body. However, they’re not as durable as flowmeters with a protective case.

PVC Fitting—PVC fittings work with a wide range of chemicals. However, they can crack from impact or when overtightened.

Brass Fitting—Brass fittings resist impact better than polypropylene and PVC fittings.

316 Stainless Steel Fitting—316 stainless steel fittings resist impact better than polypropylene and PVC fittings.

Calibration Certificate Traceable to NIST—Flowmeters with a calibration certificate traceable to NIST states that the flowmeter has passed a test for accuracy.

Panel-Mount Flowmeters for Gases

Monitor the flow rate of air and other gases from your instrument panel—these flowmeters have fittings on the back for panel mounting. They should be mounted vertically inline with your piping system, so gas flows up from the bottom. As gas passes through, it pushes an indicator up the scale, showing you the flow rate. With an acrylic body, they're completely clear, so you can inspect your gas’s color and clarity for any problems.

These flowmeters are calibrated with air but can be used with other gases. If you’re using these with a gas other than air, you’ll need to calculate the flow rate by multiplying the number shown on the scale by the specific-gravity conversion factor for your gas.

Choose a fitting material that is compatible with the gas you're running through your line.

Flowmeters with Flow-Control Knob


	Replacement Flowmeter Repair Kits

Flowmeters with a flow-control knob let you open and close the valve at the inlet to adjust the flow rate within the range.

PVC Fitting—PVC fittings work with a wide range of chemicals. However, they can crack from impact or when overtightened.

Brass Fitting—Brass fittings resist impact better than PVC fittings.

303 Stainless Steel Fitting—303 stainless steel fittings resist impact better than PVC fittings.

316 Stainless Steel Fitting—316 stainless steel fittings resist impact better than PVC fittings.

1/4 NPT Threaded Female Pipe × 1/2 NPT Threaded Male Pipe—Flowmeters with a female × male connection have internal NPT female threads and external NPT male threads.

Calibration Certificate Traceable to NIST—Flowmeters with a calibration certificate traceable to NIST states that the flowmeter has passed a test for accuracy.

Any-Orientation Flowmeters


Female	Male

A spring piston instead of a float allows these flowmeters to measure flow rate in any mounting orientation. As liquid passes through, it pushes an indicator up the scale, showing you the flow rate. They have union fittings on both ends, making it easy to position the scale so it’s visible.

These flowmeters are calibrated with water but can be used with other liquids. If you’re using these with a liquid other than water, you’ll need to calculate the flow rate by multiplying the number shown on the scale by the specific-gravity conversion factor for your liquid.

Choose a fitting material that is compatible with the liquid you intend to run through your line.

Polysulfone Fitting—Polysulfone fittings work with a wide range of chemicals. However, they can crack from impact or when overtightened.

Brass Fitting—Brass fittings resist impact better than polysulfone fittings.
