1. Structure:

YK-LB digital display target type flowmeter is mainly composed of measuring tube (shell), force element, sensing element (force sensor, pressure sensor, temperature sensor), transitional parts (increased or decreased according to temperature and pressure), and accumulated The structure of the display and output part is as follows:

1. Force component 　 2. Measuring tube (shell) 　 3. Force sensing element (including temperature and pressure sensing elements)    4, transition parts 　5, integration, display, output parts

2. Working principle:

When the medium is flowing in the measuring tube, due to its own kinetic energy and the pressure difference generated by the choke, a pair of force-receiving elements are generated. The force is proportional to the square of the medium flow rate. The mathematics The expression is as follows:

　　F=CDAρ·U2/2

　　 In the formula:

　　F——The force received by the force element

　　CD——Object resistance coefficient

　　Ρ——medium density under working conditions

　　U——The average flow rate of the medium in the measuring tube

　　A——Axial projected area of the force element on the measuring tube

     1. High temperature and high pressure resistance: from -80℃ to 350℃, the pressure can reach 42Mpa;

     2. Applicable to various calibers: Φ15-Φ1500;

     3. Suitable for liquid, gas and steam measurement;

     4. It can measure low-velocity media, and the flow velocity is greater than 0.1m/s (Reynolds coefficient is greater than 1000);

     5. Measurable medium with high viscosity and containing silt;

     6. Accurate measurement and high precision, up to 0.2% (special order);

     7. The pressure loss is small, only about 1/2△P of the standard orifice plate, and the large diameter is obviously reduced;

     8. The software is powerful, and it can be calibrated online or dry calibration;

     9. Double-line large liquid crystal display, which can display instantaneous flow, accumulated flow, over-range and battery power display;

     10. The measured flow range can be changed by replacing the force component according to actual needs;

     11. Simple and convenient installation and maintenance;

     12. A variety of installation methods, optional clamping type, flange type, thread type, plug-in removable plug-in type, sanitary type, integrated or split type.
