What is a Metal Tube Rotameter?
Metal Tube Rotameter is basically a Variable Area Flow Meter for measuring instantaneous flow rate of liquids, gases and steam applications. Metal Tube Rotameter is commissioned where there are demanding pressure and temperature constraints which a normal rotameter cannot withstand. Fully metal design body makes it a robust instrument and is extremely durable.
Scharf Automation manufactures Digital Metal Tube Rotameters which are fitted with an LCD screen with 4-20 mA / 2-Wire Transmission output, suitable for direct interfacing with PLC / SCADA system. 4-Wire Option for 4-20 mA output is also available with LED Display.
The essential working part is flow tube & precision machined magnetic float & assembly. The position of the float is sensed by a magnet and indicated on the dial in terms of flowrate by rack-and-pinion mechanism.
It can be installed in line vertically upward & horizontally towards right or towards left.
For higher accuracy applications, Turbine Flow Meter is recommended
as Digital Metal Tube Rotameters have an accuracy of 2%.
Consistent and long term performance is eminent with Metal Tube Rotameter along with durability and quality.
