Description
A flow measurement device.
D901 Flow Measurement Device is suitable for systems where pipes have been sized on the basis that pipe frictional losses lie in the range 100 to 400 Pa/m.
D902 Flow Measurement Device (1/2"/15 mm size only) is suitable for the measurement of ultra-low flows in the range 0.015 to 0.06 L/sec e.g. flows to fan coil units.
Features and benefits:
- Square edged entrance orifice plates with tappings for P84 insertion style test points.
- Flow measurement accuracy of ±5%.
