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.

90° Display Adapter Kit (Flowmeter/Totalizer Sold Separately)

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. 316 stainless steel fittings resist impact better than plastic fittings.

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. FM-approved flowmeter/totalizers are safe for use in hazardous location.

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.
