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

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

ﬂ 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.

d. The sensor assembly will then be supported by the tubings connecting

to it.

Although the operation of the Easidew PRO I.S. dew-point transmitter is not sample ﬂ 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.

To communicate with the monitor:

• Connect to the serial port using the wiring deﬁ ned below.

• Set the address of the monitor using the front panel.

• Set the desired communication protocol (ASCII or Modbus RTU) via the front panel or over the serial interface.

• Determine the register number of the parameter to be read.

• Send the correct command to the monitor and decode the response.

MODBUS RTU

Once the protocol has been set the monitor will communicate in accordance with the standard Modbus RTU protocol.

Read Holding Registers command should be used to read the registers listed in the register

The map. When two registers are listed in the table both registers must be read using a single command.

Note that the least signiﬁ cant word is sent ﬁ rst, for example - for dew point - register 40517 is the least signiﬁ cant word and 40518 is the most signiﬁ cant word.

It should also be noted that the actual address is that stated, minus 40000, i.e. 40517 is physically

There is often an offset of -1 for the register address, depending on your software/PLC system. To read the dew-point value software, read holding registers 516-517:

The highlighted value 0xFFFFFDE2 is a 32 bit signed integer .. so -542

There is a scaling multiplier of 0.1, so -542 x 0.1 = -54.2°C which is the value shown on the monitor.
