Up to 4 independent measurement channels
Customer-configurable ES70 sample systems
Optional 2-wire loop-powered O2 transmitter
Suitable for natural gas containing up to 20% hydrogen, no modification required

Overview

Promet I.S. is a heavy-duty industrial hygrometer system for measuring high-pressure process gases and vaporized liquids on natural gas platforms and terminals, petrochemical plants and industrial gas manufacturing facilities. It combines Michell's proven Ceramic Metal-Oxide moisture sensor with ES70 sample conditioning systems for a reliable, easy-to-operate, multi-channel online instrument for both flammable and non-flammable gases.

Working Principle

A Ceramic Metal-Oxide moisture sensor measures dew point directly at process pressure, fed by a customer-configurable ES70 sample conditioning system per channel. User-programmable or real-time active pressure compensation converts the raw reading into moisture content, with up to 4 independent channels available from a single control unit, optionally combined with Liquidew I.S. moisture-in-liquid or Minox-i O2 measurement functions.

Applications

Benefits

Withstands sour and glycol-contaminated gas streams that damage other sensor types
High-pressure direct measurement avoids pressure-related sampling errors
Multi-channel design consolidates several measurement points into one control unit
Can be combined with liquid moisture or oxygen measurement in the same platform
