Metal Tube Rotameters - Digital Type Transmitter

Nirmay make Digital Metal Tube Rotameter is designed taking industrial applications into focus. The Light weight and Explosion proof body makes it a highly suitable instrument to be used in hazardous environments.

Pros of the Digital Variable Area Flow Meter :
Local Indication without the need of auxiliary power
Minimum pressure loss
Easy to read
Accurate measurement even at higher flow (150 M3/Hr)
Suitable for low flow (8 LPH)
Default inbuilt transmitter of 4-20 mA (Loop Powered)
No movement assembly reducing the maintenance

It operates on the principle of Variable Area; the fluid in the metal tube raises a float in the taper tube increasing the area for passage of fluid. The float moves up in proportion to the rate of flow of fluid and get stabilized when the weight of the float is balanced by the upward hydraulic force. The flow rate is determined by the combined effect of the float movement and the magnetic field changes relative to the float movement. As such this flow meter does not require any electrical connection since it operates on battery. It has an inbuilt two wire transmitter provide 24VDC and take 4-20 mA .
