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.

Flowmeter/Totalizers for Water

With a display that can be placed up to 25 feet from the sensor, these flowmeter/totalizers are often used in hard-to-access areas. For a complete unit, order a display, a sensor, and a tee fitting.

Display can be programmed to show flow rate in gallons or liters per second, minute, hour, or day. It has an enclosure that meets NEMA 4X for protection from dust, washdowns, and corrosion.

Sensor installs in a tee fitting (sold separately). It includes 25 feet of cable with wire leads.

Tee fitting has two unthreaded female socket end connections; connect with PVC cement and primer.

Washdown Flowmeter/Totalizers for Water

For protection from dust, washdowns, and corrosion, these flowmeter/totalizers have an enclosure that meets NEMA 4X. They measure both the flow rate and the total flow volume of water. Reset the total flow volume to zero with the reset button. The reset function can be disabled to prevent tampering.
