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. Features
3. Application
Turbine Flowmeter is widely used in the following measurement objects: oil, organic liquid, inorganic liquid, liquefied gas, natural gas, gas and cryogenic fluid and so on. It is widely used for trade settlement at the transshipment and gathering stations of liquefied petroleum gas, refined oil and light crude oil abroad, and at the first and last stations of large crude oil pipelines. In Europe and the United States, turbine Flowmeters are natural gas meters second only to orifice Flowmeters. Only in the Netherlands, more than 2600 gas turbine Flowmeters of various sizes and pressures from 0.8MPa to 6.5MPa have been used in natural gas pipelines. 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 with short service life and hesitation in selection. Through people's unremitting efforts, it should be said that the situation has greatly improved.Turbine Flowmeter as the most general Flowmeter, its products have been developed into a multi-variety, full-series, multi-specification mass production scale.
In addition to the extensive application of the turbine Flowmeter in the above-mentioned industrial departments, it has also been widely used in some special departments, such as scientific research and experiments, national defense science and technology, and metrology departments. The use of these fields just avoids its weakness (not suitable for long-term continuous use). Give full play to its characteristics (high precision, good repeatability, can be used for high pressure, high temperature, low temperature and micro-flow conditions). In these fields, most of them carry out special structural design according to the special requirements of the tested object, and they are special instruments that do not carry out mass production.
