INTRODUCTION

1.5 Sampling

System

The Promet I.S. requires a clean sample of the gas mixture that meets the pressure and

ow requirements of the transmitter. The design of the sampling system will depend

on the speci

c application.

The requirements for the sample gas going into the sensor block are as follows:

•

Temperature: -40 to +60°C (-40 to +140°F)

(-20 to +40°C (-4 to +104°F) recommended for optimum performance)

•

Maximum pressure: 45 MPa (450 barg / 5801 psig)

•

Flow rate: 1 to 5 Nl/min (2.1 to 10.6 scfh)

NOTE: Contact Michell Instruments if you wish to order a speci

c sampling

system.

Please refer to the Promet I.S. Premium Sampling System Instructions if a Michell

sampling system has been ordered with the Promet I.S.
