About Flowmeters and Totalizers
Flowmeters measure the rate of flow for a liquid or a gas. Totalizers measure the cumulative flow volume. Flowmeter/totalizers display both the flow rate and the cumulative flow volume.

Easy-Read Flowmeters

A large dial instead of a scale makes it easier to read the flow rate from a distance. As liquid flows through these flowmeters, it pushes a needle along the dial, showing you the flow rate. They measure flow correctly no matter the mounting orientation.
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 direction of flow that matches your pipe system, so you don't have to tilt your head to read the dial.
Choose a fitting material that is compatible with the liquid you're running through your line. PVC fittings work with a wide range of chemicals. However, they can crack from impact or when overtightened.

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. PVC, nylon, and PVDF plastic fittings work with a wide range of chemicals. However, they can crack from impact or when overtightened.
Flowmeter/totalizers with a calibration certificate traceable to NIST include documentation that states they’ve passed a test for accuracy.
IP rated, all seal out dust and can be lightly rinsed. NEMA 4 flowmeter/totalizers protect against weather and washdowns.
90° display adapter kits let you rotate the meter’s display 90°, so you can read it easier when mounted vertically.
Output modules allow you to transmit flow data from flowmeter/totalizers to an external device such as a programmable logic controller (PLC), data recorder, logger, and remote display (not included). 4-20 mA output modules have an analog output. As flow increases, the output signal from the transmitter increases. For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the measurement range and output signal of the transmitter. They only give accurate readings within the rated measurement range. Pulse output modules have a digital output. They transmit flow data using spikes of voltage that match the input voltage of the transmitter. The higher the flow, the more pulses they send.
Remote panel-mounting kits let you mount the meter’s display up to 10 feet away.

Socket-Connect Flowmeter/Totalizers
The unthreaded ends of these flowmeter/totalizers install into a PVC piping system, so you can measure the flow rate and volume of liquid passing through your system. Bond the joint together with PVC cement and primer. You can reset the batch total, but you can't reset the cumulative total. They measure flow correctly no matter the mounting orientation.
These flowmeter/totalizers are calibrated with water.
Turbine flowmeter/totalizers measure flow by counting how many times their turbine turns as liquid passes through. To avoid clogging the turbine and other damage, use them only with clean, low-viscosity liquids. You can recalibrate them in the field to other liquids, pipe, and operating conditions.
Ultrasonic flowmeter/totalizers measure flow with ultrasonic waves, so they don’t have internal moving parts that can break or get stuck.
Output modules allow you to transmit flow data from flowmeter/totalizers to an external device such as a programmable logic controller (PLC), data recorder, logger, and remote display (not included). 4-20 mA output modules have an analog output.

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

Calibration Columns

Calibrate the flow rate of metering pumps. A graduated scale with zero at the top lets you easily see how much fluid is lost over the course of a one-minute test. This will tell you your pump’s flow rate. Periodic testing helps alert you to issues in your system, such as worn or dirty valves. Checking the flow rate after performing maintenance ensures your pump is working properly.
Install the column between your reservoir and pump. They require shutoff access to your reservoir and an on/off valve (not included) at the point where they connect to your system. To start the test, open the on/off valve as the system is running to fill the column with fluid up to the zero mark. Shut off the valve and wait one minute before observing the liquid level in the column. After you've taken the reading, close the on/off valve to the column and reopen access to the reservoir.
PVC calibration columns are a good choice when working with water.
