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.

Remote-Reading Socket-Connect 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.

Flowmeter/Totalizers for Water

Determine the flow rate and total flow volume of water with the same meter. The batch total volume can be reset after each metering application. The total flow volume cannot be reset.

Certificate of calibration traceable to NIST states that the flowmeter/totalizer has passed a test for accuracy.

FM-approved flowmeter/totalizers are rated for environments where hazardous material is present. Hazardous location environmental ratings indicate where manufacturers have included safety features in products to facilitate their safe use in hazardous environments. Before selecting a product for a hazardous location, ensure it is rated for your environment. See About Hazardous Location Environmental Ratings.

Flowmeter/totalizers with a NEMA-4 rated enclosure are protected from dirt and washdowns.

Flowmeter/Totalizers for Water and Chemicals

To withstand water and a variety of caustic chemicals, these flowmeter/totalizers have a corrosion-resistant 316 stainless steel body. They measure both flow rate and total flow volume. The batch total volume can be reset after each metering application. The total flow volume cannot be reset. They have an enclosure that meets NEMA 4 for protection from dirt and washdowns.

Flowmeter/totalizers with threaded connections have 316 stainless steel seals, which resist corrosion.

Connect flowmeter/totalizers with quick-clamp connections to other quick-clamp fittings (often called tri-clamp fittings) using a gasket and clamp. They’re easy to attach and remove for cleaning.

Certificate of calibration traceable to NIST states that the flowmeter/totalizer has passed a test for accuracy.

Optional output module transmits output signals to an external device such as a data recorder, logger, or remote display (not included). It includes 10 feet of cable with wire leads.

Optional remote panel-mounting kit lets you mount the meter’s display up to 100 feet away. It includes a sensor module and 10 feet of cable with wire leads.

Hazardous location environmental ratings indicate where manufacturers have included safety features in products to facilitate their safe use in hazardous environments. Before selecting a product for a hazardous location, ensure it is rated for your environment. See About Hazardous Location Environmental Ratings.
