Industrial Water Flow Meter / Gas Meter / Turbine Flow Meter
1. Introduction
LWGYML series intelligent liquid turbine flow meter is a new type of intelligent instrument with integrated turbine flow sensor and display product calculation developed by advanced ultra-low power single-chip microcomputer technology, which has obvious advantages such as compact mechanism, clear reading, high reliability, undisturbed by external power supply, lightning resistance and low cost.
2. 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.
