How to choose this product
counter

A counter indicates an accumulated or flow quantity.

Applications

Many different kinds of counters are used throughout industry, including petroleum and chemical installations, dialysis machines or as electrical meters.

Technologies

Such devices can be digital, electromechanical or, occasionally, pneumatic. The display may have a built-in or remotely controlled zero reset button. A pulse counter responds to discrete signals from a measuring device.

A single- or three-phase electrical meter records energy consumed by a load or produced by a generator. It often indicates voltage, intensity, active, reactive and apparent power, power factor and the frequency and rate of harmonic distortion.

Particle counters are used in clean rooms or to monitor the air in work settings. They indicate the relative number of dust particles by size. Geiger counters measure radioactivity.

Oval wheel meters measure fluid volume flow in chemistry and agribusiness. An hour-meter indicates the elapsed running time of a machine or a process.

Counters can have a Modbus, Ethernet or WiFi network interface, or an RS232 or RS485 serial connection. Successive measurements are stored in memory.

How to choose

Counters are characterized by the number of digits they can display, their measurement and reset method, and the number of communication ports available.
