To have the real flow with the use of low temperature glycol solutions, it is necessary to multipy the value indicated by the flowmeter by a corrective factor, that is:
  • 0,9 for concentrations of 20-30%
  • 0,8 for concentrations of 40-50%

Adjustment:
The reading of the flow is done at the lower part of the mobile indicator.
The valve can be mounted in horizontal or vertical position with any sense of flow. For an accurate and stable reading please provide a straight pipe with an overal length of at least 5 times the diameter of the pipe.
