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.

Wire these counters up to an electrical pulse-emitting switch, sensor, or encoder for use on machine tools, packaging machinery, or other equipment.

Non-resettable counters prevent tampering and accidental loss of data.

Panel-Mount Electrically Actuated Counters with Output Relay

Wire these counters up to an electrical pulse-emitting switch, sensor, or encoder for use on machine tools, packaging machinery, or other equipment. They have two displays. One display shows a set point and the other counts incoming pulses. When the counter reaches the set point, an output relay sends a signal to another device. The signal can start/stop a process or trigger an alarm.

Electrically Actuated Hour Meters with Output Relay

Display running time on a machine so you can schedule preventative maintenance. These counters have two displays. One display shows the total running time and cannot be reset; the other shows the time elapsed since the last maintenance and can be wired for remote reset. The output relay turns on an indicator light and sends a signal to another device when the counter reaches a set point. The signal can start/stop a process or trigger an alarm.

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.

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

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.
