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.

Send flow-rate readings to data recorders, loggers, and displays.

Transmitters with a 316 stainless steel body are more corrosion resistant than transmitters with a brass or polypropylene body.

Compact Flow Transmitters for Water

Use these transmitters in areas with limited clearance to send flow-rate readings to data recorders, loggers, and displays. They have a 316 stainless steel body for corrosion resistance in harsh environments.

Optional display meter accepts flowmeter output signals and registers flow rate and total. The display can be manually reset.

Flow Transmitters for Air

Calibrated for compressed air, these transmitters send flow-rate readings to data recorders, loggers, and displays. They have compression tube connections that bite down on hard metal and plastic tubing for a secure seal. The digital display shows the flow rate, so these transmitters can also be used as flowmeters. Fittings are 316 stainless steel for corrosion resistance in harsh environments.
