- Local indication without the need for auxiliary power. Minimum pressure loss.
- Easy to read.
- Accurate measurement even at a higher flow (150 M ³ /Hr).
- Suitable for low flow (8LPH)
- Default inbuilt transmitter of 4 â 20 mA (Loop powered).
- No movement assembly reducing the maintenance.
- FLOWTECH make Digital Metal Tube Rotameter is used for flow measurement where current output with totalizer is required.
It operates on the principle of variable area. The fluid in the Metal Tube raised afloat in the tapered tube increasing the area of passage of fluid. The float moves up in proportion to the rate of flow of fluid and gets stabilized when the weight of the float is balanced by the upward hydraulic force. By a magnetic coupling the inner float movement through a series of linkages and counterweight. The tube and the float combination determine the flow rate. DIGITAL METER:- The inner float magnetic field is detected by the high sensitive magnetic field detection sensor, enable us to show the digital readout. As such this flow meter does not require any electrical connection since it operates on battery. It has an inbuilt two-wire transmitter provides 24 VDC and take a 4 â 20 mA signal.
