HVPF Swirl Flow Meter Product Introduction The intelligent swirl flow meter is a new type of gas flow meter. The flow meter integrates flow, temperature, and pressure detection functions, and can automatically compensate for temperature, pressure, and compression factor. It is an ideal instrument for gas measurement in petroleum, chemical, electric, metallurgical and other industries. Product Features ●No mechanical moving parts, not easy to corrode, stable and reliable, long life, long running without special maintenance; ●Use 16-bit single chip, high integration, small size, good performance,...

●Converter can output pulse frequency, 4 ~ 20 ma analog signals, with RS485 interface, can be directly with the computer networking, transmission distance of 1.2 km; ●Multi-physical parameter alarm output, users can choose one of them; ●Flow meter header can rotate 360 degrees, easy to install and use; ●With our data collector, remotely transmit data through the Internet or telephone network; ●The pressure and temperature signals are sensor input methods, which are highly interchangeable; ●Low power consumption, internal battery or external power supply available; ●Maintenance-free, cleaning-free....

6. Piezoelectric crystal sensor The frequency signal of swirl precession can be detected by installing it near the throat of the shell expansion section. 7. Disappear is investigated Fixed in the outlet section of the shell, its function is to eliminate swirl flow, so as to reduce the impact on downstream instrument performance. Working Principle The flow profile of the flow sensor is similar to the profile of the Venturi tube (Figure 2). A set of spiral guide vanes are placed on the inlet side. When the fluid enters the flow sensor, the guide vanes force the fluid to produce a violent swirl....

Less than 1/3 of the absolute value of the basic error limit Note: 1. Accuracy: refers to the system accuracy after temperature and pressure correction; 2. A and B are used to distinguish different flow ranges with the same diame
