1.1
Introduction
The PD 340 Flow Transmitter is a precision meter for the volumetric measurement of liq-
uids that are electrically conducting.
The rugged construction of the transmitter makes it suitable for installations where solid par-
ticulates make up part of the liquid for measurement.
This manual is applies to PD 340 Flow Transmitters that utilise the 'Version 2' electronics
module.
