    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.

    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.

    Flowmeter/Totalizers

    Determine the flow rate and total volume of liquid flowing through your system with the same meter. To measure flow, these flowmeter/totalizers count how many times their turbine turns as liquid passes through. Use them only with clean, low-viscosity liquids to avoid clogging the turbine and other damage to these flowmeter/totalizers. You can reset the batch total, but you can’t reset the cumulative total. Mount them inline with your pipe system. They’re accurate in any mounting orientation.
    These flowmeter/totalizers are either calibrated with water or solvent. You can recalibrate them in the field to other liquids, pipe, and operating conditions.
    Choose a fitting material that is compatible with the liquid you're running through your line. IP rated, all seal out dust and can be lightly rinsed.

    Accessories for Flowmeters

    Socket-Connect Flowmeter/Totalizers with Remote Display

    Often used in hard-to-access areas, these flowmeter/totalizers have a display that can be placed up to 25 feet from the sensor. Use them to measure the rate and volume of liquid flowing through your system. They measure flow by counting how many times their turbine turns as liquid flows through. To avoid clogging the turbine and other damage to the sensor, use them only with clean, low-viscosity liquids. Batch totals are resettable but can be protected with a security code to prevent tampering. The reset function can also be disabled so that they operate as a cumulative totalizer. Cumulative totals cannot be reset. No matter the mounting orientation, they’ll measure flow correctly.
    These flowmeter/totalizers are calibrated with water. You can use them with other liquids, but they may not measure accurately if the liquid’s viscosity differs from water.
    For a complete unit, you’ll need a display, a sensor, and a tee fitting.
    Tee Fittings

    Tee fittings mount inline with your pipe. They have two unthreaded socket ends that bond to unthreaded PVC pipe with PVC cement and primer.

    Flanged ends let you securely integrate these totalizers into large drinking water pipelines to measure the cumulative amount of water flowing through them. They meet NSF/ANSI 61, so they're safe to use with drinking water. They measure flow volume by counting how many times their turbine turns as liquid flows through. To avoid clogging the turbine and other damage to the sensor, use them only with clean, low-viscosity liquids. Their total cannot be reset.
    These totalizers are calibrated with water. You can use them with other liquids, but they may not measure accurately if the liquid’s viscosity differs from water.
    Flanges—The elliptical flange kit (sold separately) lets you convert elliptical flanges to NPT female connections.
