INTRODUCTION

The Liquidew I.S. Process Moisture Analyzer is a continuous, on-line instrument for
the measurement of absolute moisture content in a liquid. It is designed to fulfi l a
wide range of applications and provide for the monitoring and/or control of moisture
in liquids. The instrument consists of two component parts: the control unit and the
sensors (moisture and temperature transmitters). They are individually calibrated to a
single standard allowing for total interchangeability between combinations of sensors
and control units.
The range of the instrument is from 0 to 500 parts per million by weight (ppm
are 8 pre-set liquid options available for the C
together with 2 user-defi ned solutes and an ability to mix any 2 liquids from the list.
Four alarm relay contacts are provided which are user-confi gurable in set-point and
operating mode. The current output is factory set at 4-20 mA.
The Liquidew I.S. Control Unit must be placed in a non-hazardous area suitable for
electronic analytical equipment. The moisture and temperature transmitters can be
positioned close to the process sample take-off point in a Zone 0, 1 or Zone 2 (Class I,
Division 1, Groups A, B, C & D) hazardous area. The control unit and transmitters are
connected via a standard 2-wire instrumentation cable protected by safety isolation
interface units.
