3.4.  Required Length of Straight Pipe

The flow sensor should be installed as far as possible from disturbances of the flow. The causes for distur-

bance of the flow are for instance, reducers, elbows, T-pieces, valves, gate valves, etc. The specified meas-

urement accuracy can be achieved only when the following straight inlet and outlet pipe lengths are installed:

• 

The wall thickness of the inlet and outlet pipe should be 2.6 mm

• 

The stated values are as a minimum. If possible, allow for greater distances.

• 

Valves or gate valves should be installed downstream of the flow sensor.

• 

With lighter gases the inlet straight pipe should be longer.
