ZWZDH wedge throttling device is a new type of throttling device developed by our company. Its special structure, non clogging, solid structure and long service life can be used to measure liquid, gas and steam, especially for flow measurement of low flow rate, high viscosity, dust or solid particles and other fluids, such as crude oil, fuel oil, residue, coal tar, wastewater, carbon black solution and other fluids.

Nozzle flowmeter

1. ISA1932 nozzle (also known as standard nozzle): Standard nozzle is composed of two circular curved surfaces, the contraction part of the inlet and the cylindrical throat connected with it. It has simple structure and convenient installation. Throttle parts can resist erosion at high temperature and high pressure and have long service life. Suitable for measuring high-pressure steam, high-pressure water, natural gas, the highest pressure can reach 42 MPa, the highest temperature can reach 1000 C, the range ratio of nozzle is 1:3-1:5, good repeatability, no real-flow calibration, only checking the shape and geometry size, accuracy can reach (+1%); suitable for the occasion of trade settlement. The pressure of standard nozzle is taken by angular connection. According to the connection mode, it can be divided into direct welding form and flange connection form. In order to facilitate field installation and improve measurement accuracy, it can provide straight pipe section along with goods. It can also make integral connection of the pressure taking part into an integrated form.

Turbine flowmeter

I. Overview The liquid turbine flowmeter is a new generation of turbine flowmeter, which absorbs the advanced technology of flow meters from domestic and abroad and is optimized, with the characteristics of simple structure, lightweight, high precision, good reproducibility, sensitive reaction, easy installation, maintenance and use. It is widely used to measure closed pipes, for measuring liquids that has no corrosive effect with stainless steel 1Cr18Ni9Ti, 2Crl3, corundum A1203 and cemented carbide, without impurities such as fibers, granules, etc., and the kinematic viscosity is less than 5×10-6mm/s at working temperature. For liquids with kinematic viscosity greater than 5×10-6mm/s, the flowmeter can be used after calibration with the real liquid. If matched with display instruments with special functions, it can also carry out quantitative control, excessive alarm, etc. It is an ideal instrument for flow measurement and energy saving.
