Sampling System
The Promet I.S. requires a clean sample of the gas mixture that meets the pressure and
fl ow requirements of the transmitter. The design of the sampling system will depend
on the specifi 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 specifi 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.
