The device can be installed in either horizontal or vertical pipes, but following additional conditions should be respected:

• The pipe always has to be filled with fluid at all times near the device.

• The pipe design must be such that no air bubbles or cavitation can form within the medium near the device at any time.

Pressure and temperature ratings must be respected according to the selected fitting material. The suitable pipe size is selected using the

diagram in the chapter “Nominal size selection” of the data sheet Type S020 .

6.2. Mounting options

It is advisable to mount the flowmeter at a 45° angle to the horizontal centre of the pipe to avoid having deposits on the electrodes and false

measurements due to air bubbles

Product operation

7.1. Measuring principle

The E-shaped magnetic system inside the sensor induces a magnetic field into the fluid, which is perpendicular to the direction of flow. Two

electrodes are in galvanic contact with the liquid.

Based on the Faraday law a voltage can be measured between these electrodes once a liquid (min. conductivity of 20 µS/cm) flows along

the pipe. This voltage is proportional to the flow velocity.

Using the K-factor for the individual pipe diameter the speed of flow is converted into volume per time.
