Welded pipe openings measured 3.1 on the mounting base is larger than the base ￠ 51 tube ￠ 51 tube is inserted into the base for the pipe at the depth of the openings on both sides of the weld flat glass rotor flowmeter how much shown; 3.2 stainless steel welding rod welding, after welding to ensure that the flange surface parallel to the axis of the tube, 4. Installation 4.1 Cleaning the sensor mounting base of the test tube welding slag and burrs. 4.2 DN50 ball valve mounted on the mounting base, pay attention to ball up the sky chamber glass rotor flow meter parameter, check valve switch properly. 4.3 clamping threaded mount kit to the valve, loosen the screw and the compression nut, insert the sensor rod is inserted through the ball valve for the pipe. 4.4 Sensor insertion depth is extended outside the base 3mm, meet the requirements, tighten the positioning screw and clamping nut. Also note signs consistent with the fluid flow direction sensor. WELKIN's WFU series of ultrasonic flowmeter using the time differential principle. The measured fluid by the two pairs of ultrasonic generator and receiver two channels glass rotor flowmeter manufacturer, a channel ultrasonic wave emitted by the downstream direction, the upstream direction to another channel by emitting ultrasonic waves. Because ultrasound during "downstream" and "upstream" through the measured fluid used at different times, and the fluid flow rate and the time difference ΔT to form a single-valued function. Therefore, the time difference ΔT measured flow rate can be calculated, then come to traffic volume.
