Flange Type Turbine Flow Meter with Explosion Proof DN80 Low Price
1. Introduction
LWGYML series turbine flow meter is a new generation kind of flow meter that absorbs the advanced technologies of flow meter at home and abroad. It has been optimized and designed to have so many characteristics, such as simple structure, light weight, high precision, good repeatability,easy installation and usage.
It is widely used in the sealed pipelines which doesn’t have corrosion function on SS 1Cr18Ni9Ti, 2Cr13, corundum Al2O3 and cemented carbide and have no fiber, particle and so on. The liquid should be less than 5*10-6m2/s with viscosity under working temperature, if the viscosity of the liquid is more than 5*10-6m2/s, then the flow meter can be used after calibration. If it is equipped with other display devices with special functions, it can also do quantity control, excessive alarm and so on. It is really perfect in flow measurement and energy
conservation.
2. Features
3. Application
Turbine flowmeter is widely used in the following measurement objects: petroleum, organic liquid, inorganic liquid, liquefied gas, natural gas, coal gas and cryogenic fluid. In foreign countries, liquefied petroleum gas, refined oil and light crude oil are used for trade settlement in the first and last stations of large crude oil pipelines. In Europe and the United States, turbine flowmeter is second only to orifice flowmeter, while in the Netherlands alone, more than 2,600 turbine flowmeters with various sizes and pressures ranging from 0.8MPa to 6.5MPa have been used in natural gas pipelines, and they have become excellent natural gas flowmeters. Although the excellent metering characteristics of turbine flowmeter are favored by people, it gives people the impression that it is made up of moving parts and has a short service life, so it is inevitable to hesitate when choosing them. After people's unremitting efforts, it should be said that the situation has changed greatly. As the most universal flowmeter, the turbine flowmeter has developed into a mass production scale with multiple varieties, full series and multiple specifications. Turbine flowmeter is widely used in some special departments besides the aforementioned industrial departments, such as scientific research and experiment, national defense science and technology, and metering departments. The use of these fields just avoids its weakness (not suitable for long-term continuous use) and gives full play to its characteristics (high precision, good repeatability, and can be used in high pressure, high temperature, low temperature and micro-flow conditions). In these fields, most of them are designed according to the special requirements of the measured objects, and they are special instruments without mass production.
