1 INTRODUCTION
The Promet I.S. Process Moisture Analyzer is a continuous, on-line instrument for the measurement of absolute moisture content in gas. It is designed to fulfi l a wide range of applications and provide for the monitoring and/or control of moisture in gas. The instrument consists of two component parts: the control unit and the sensors’ assembly (moisture transmitters and optional pressure transmitter). They are individually calibrated to a single standard allowing for total interchangeability between combinations of sensors and control units.
The instrument covers the ranges –100 to +20°Cdp ( -148 to +68°Fdp), 0 to 9999 ppm
as well as 0 to 1000 lb/MMscf and g/m3 for natural gas. Selection of the displayed
V
moisture unit of measure is factory-set but may be easily changed by the user. Four alarm relay contacts are provided which are user-confi gurable both in terms of set-point and operating mode. Current output is factory set at 4-20 mA.
The Promet I.S. performs moisture content calculations based on the measured dew point and the analysis pressure. The default setting of the monitor assumes atmospheric pressure but the customer can set a fi xed value of elevated pressure - for this to be a valid method, the sensor must be installed at a constant, known analysis pressure. Alternatively, there is an active pressure compensation option providing a loop-powered intrinsically-safe pressure transmitter connecting to the second input channel on the control unit, for dynamic pressure compensation.
INTRODUCTION
The Promet I.S. Control Unit must be placed in a non-hazardous area suitable for electronic analytical equipment. The moisture transmitter and optional pressure transmitter can be positioned close to the process sample take-off point in Zone 0, Zone 1 or Zone 2 (Class I, Division 1, Groups A,B,C and D) hazardous area. The control unit and transmitters are connected via a standard 2-wire instrumentation cable protected by safety isolation interface units.

1.3 Theory of Operation
The reliable and robust sensor design is fundamental to achieving accurate measurement of moisture in process over a long period of time. Proprietary thick- and thin-fi lm techniques are applied in the Michell Ceramic Moisture Sensor. The inert materials of the sensor have a high resistance to aggressive media while the inherent strength of the sensor and the thermal bonded connections to the active device ensures reliable operation.

Figure 2
Structure of the Michell Ceramic Moisture Sensor
The ceramic sensor responds to the partial pressure of water vapor in the gas being measured, which is directly related to the dew-point temperature.
Calibration is certifi ed traceable to NPL (UK) and NIST (USA) through the use of dew- point transfer standards.
The fi rmware of the Promet I.S. incorporates dew point/pressure to moisture content conversion data for ideal gas and natural gas. The calculation for natural gas uses either the long established IGT research Bulletin No.8 or the more recently published ISO 18453, depending on the customer’s preference.

b. The dew-point transmitter has a 5/8” UNF parallel mounting thread which
should be installed directly into the sampling block with the bonded seal provided. The bonded seal provided should be placed over
the transmitter mounting thread before it is screwed into the sampling block.
c. Finger tighten the dew-point transmitter by gripping the spanner/wrench
ats on the body - NOT the transmitter body cover. Completely tighten using a spanner/wrench until the bonded seal is fully compressed to a minimum torque of 30.5 Nm (22.5 lbf-ft).
INSTALLATION
d. The pressure transmitter has a 1/8” NPT thread. It can be installed into
the 1/8” NPTF port on the sensor block. Follow the standard Swagelok installation instructions to make the connection.
To install the complete Promet I.S. sensor assembly into the sampling system, follow these steps:
a. Select a location to mount the sensor assembly which has suffi cient
clearance for connecting and disconnecting the inlet/outlet tubing and cable. The surface should be strong enough to hold the analyzer.
b. Mount the Promet I.S. sensor assembly into the sampling system via its
two mounting holes.
c. Sample gas connections are made via the gas inlet and gas outlet ports as
shown in ports. Michell recommends using Swagelok® 6mm to 1/8” NPT (ordering code SS-6M0-1-2) or 1/4” to 1/8” NPT (ordering code SS-400-1-2) male connectors to connect these two ports to the 6mm or 1/4” sampling system tubing. Follow standard Swagelok® installation instructions to make the connections.

Although the operation of the Easidew PRO I.S. dew-point transmitter is not sample ow-rate dependant, it is important to ensure that the fl ow velocity through the sample line to the sampling block is high enough to avoid long time lags in response to changes in moisture at the sample source. Michell recommends that a fl ow-rate of 1 to 5 Nl/min (2.1 to 10.6 scfh) (or equivalent at pressure) be set and that the dew-point transmitter is mounted as close as practicably possible to the sample source.
