PEM-1000 - Electromagnetic Flowmeter for Connection & Configuration

Electromagnetic Flowmeter Type PEM-1000

Application

Electromagnetic flowmeter for bidirectional measurement of liquids with a minimum conductivity of 5 S/cm:

Acid, alkalis
Paints
Pastes
Water, Wastewater, etc.

Measuring principle:

Following Faraday's law of magnetic induction, a voltage is induced in a conductor moving through a magnetic field. In the electromagnetic measuring principle, the flowing medium is the moving conductor. The voltage induced is proportional to the flow velocity and is supplied to the amplifier by means of two measuring electrodes. The flow volume is calculated by means of the pipe cross-sectional area.The DC magnetic field is created through a switched direct current of alternating polarity.

Measuring System:

The measuring system consists of a transmitter and a sensor. Two versions are available:

Compact version: Transmitter and sensor form a mechanical unit PEM-1000ALW
Remote version: Sensor is mounted separate from the transmitter PEM-1000NW

Advantages

Flexible and clever assembling system
Easy and fast-moving change from compact to remote version
Innovative and high-power transmitter for every application
Robust and resistant cover of sensor and transmitter
