Intelligent Alcohol Turbine Flow Metre Pulse Output -20℃~+110℃ Medium Temperature
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.
2. Features
- High accuracy, usually reach ±1%R,±0.5%R,or even reach ±0.2%R for high-precision type.
- Good repeatability, it can reach 0.05%-0.2% in short term, if regular calibration or online calibration can get an extremely high accuracy, so it is preferred in foreign trade.
- Pulse signal output, it is suitable for totalizer measurement and computer connection, no zero drift,strong capacity of resisting disturbance.
- High frequency signal(3-4KHz), strong signal resolution.
- Wide range, middle and big diameter can reach 1:20, and small diameter can reach 1:10.
- Compact structure, easy installation and maintenance.
3. Application
Turbine flowmeter is widely used in the following measurement objects: petroleum, organic liquid, inorganic liquid, liquefied gas, natural gas, gas and cryogenic fluid. It is widely used in foreign LPG, refined oil and light crude oil transfer and gathering stations, as well as in the initial and terminal stations of large crude oil pipelines for trade settlement. In Europe and the United States, turbine flowmeter is second only to orifice flowmeter for natural gas metering. Holland alone has adopted more than 2600 gas turbine flowmeters with various sizes and pressures ranging from 0.8MPa to 6.5MPa on natural gas pipelines. They have become excellent natural gas flow meters. Although the excellent metering characteristics of turbine flowmeter are favored by people, it gives the impression that it is composed of moving parts with short service life, which makes it hesitant to select it. After unremitting efforts, it should be said that the situation has been greatly improved. As the most common flowmeter, turbine flowmeter has been developed into a large scale of multi variety, full series and multi specification batch production.
Turbine flowmeter is widely used in some special departments, such as scientific research and experiment department, national defense science and technology department and measurement department. 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 tested object. They are special instruments and do not carry out mass production.
