Flowmeter
The PD 340 Flowmeter is an electromagnetic precision meter for the volumetric measurement of liquids that are electrically conductive. The transmitter can be used in applications where a hygienic design is required.
The rugged construction of the transmitter makes it suitable for installations where solid particles are present in the liquid.
Flowmeter advantages
Suitable for sanitary applications: Designed especially for the food industry.
No moving parts: No maintenance.
Robust and compact design: Easy to mount, even in difficult applications.
Factory configured to suit customer requirements: Makes installation easy and saves time and money.
Constructed to be independent of variations in flow profile: High accuracy, even if the viscosity or the liquid changes. Change between different media, such as milk, cream, and liquids containing solids, without any need for recalibration.
Optimised for high accuracy and linearity: Using the linearising function, it is possible to measure within a 1:100 turn down range. Therefore, the meter can normally be chosen to have the same size as the diameter of the pipe work, and the cost of installation and any pressure drop can be minimised.
Volumetric measurement in: m3, litres, U.S. gallons etc.

Flowmeter construction
- Meterhead - consists of a stainless metering pipe with clamp liners. Two magnet coils are mounted external to the metering pipe. Inside the metering pipe two stainless electrodes are mounted. The measuring section is designed so that changes in flow profile do not affect meter accuracy.
- Electronic module - two versions are available: Standard and Extended. Extended version has extra digital output (pulse output), which can be configured as a standard 4-20 mA current output or 3-phase output.
- Terminal box - completely separated from the electronic module. Connections can therefore be changed without disruption to the electronics. Terminals for PD210 connection are available.
