Measuring and monitoring flow and pressure

The devices in this category measure or monitor what flows in a pipe: a flow switch to detect whether there is a flow, a flowmeter to know the volume, a pressure transmitter to follow pressure. They are used to protect a pump or to control an installation.

Which device for which need

  • Flow switch: on-off contact depending on the presence of flow.
  • Electromagnetic flowmeter: flow measurement of a conductive liquid.
  • 4-20 mA pressure transmitter: analogue signal for a controller or a drive.

Frequently asked questions: Flow and pressure control

What is a flow switch for?

It detects whether water is flowing or not in the pipe. It is used to stop a pump when there is no flow or to signal a fault. Check the pipe diameter and the maximum pressure on the product page.

What does a 4-20 mA signal mean?

It is an analogue current signal that sends the measured value to a controller or a drive. The transmitter must have a pressure range suited to the installation.

Is a flowmeter suitable for all liquids?

An electromagnetic flowmeter measures conductive liquids. Check the product page for the liquid accepted, the diameter and the installation conditions.
