Turbine flow meter factory show:
1.What is the material of construction?
· Body and vanes – 304SS
· Bearings and Shaft – tungsten carbide (alternates are available for special applications)
· Rotor – 2GR13(Two way steel is optional) See the Flow Meter Rotor Alloy 2GR13 data sheet for chemical composition information.)
2.. What are the different types of liquid meters and what are their benefits?
· Standard grade
· Industrial grade (for improved linearity)
3.What problems will make a liquid meter read inaccurately?
Debris in the meter, a broken shaft, viscous fluids, gas in flow line and/or improper sizing or installation can cause in accurate readings.
