Product Description

Digital Metal Tube Rotameter with Totalizer works on the law of variable area - the fluid in metal tube upraised a float in taper tube, which increases the area of fluid passage. The float moves up in proportion to fluid flow rate and get stable when the float weight is balanced through upward hydraulic force. With a magnetic coupling, the movement of inner float by a series of counter weight and linkages. The tube as well as the float unit determines the rate of flow.

Digital Meter: High sensitive sensor for magnetic field detection is there to find out the inner float magnetic field. It enables us to display the digital read out. As it operates on battery, this flow-meter does not involve any electrical connection. It has built-in two wire transmitter that provides 24 VDC and take 4-20 mA signal.
