TRH-L-F1 floating ball flow sensor, economical flow calculation instrument

The typical structure of a metal tube float flowmeter with a right angle installation method is usually suitable for instruments with a diameter of 15-40mm or more. Cone tube 5 and float 4 form a flow detection element. There is an extension of the guide rod 3 inside the casing (not shown in Figure 3), which transmits the displacement of the float to the conversion part outside the casing through magnetic coupling and other methods. The conversion part has two types: local indication and remote signal output. In addition to the right angle installation method, there is also a straight through structure where the centerline of the inlet and outlet is concentric with the cone tube, which is usually used for instruments with a diameter less than 10-15mm.
