304SS Turbine Industrial Flow Meter 4-20mA Flange Connection Big Diameter
1. Introduction
LWGYML series intelligent liquid turbine Flowmeter is a new intelligent instrument which integrates turbine flow sensor and display. It is developed by using advanced ultra-low power single chip microcomputer technology. Compact structure, clear reading, high reliability, no external power interference, lightning protection, low cost and other obvious advantages
Turbine flow meters are widely used in the following measurement objects: oil, organic liquid, inorganic liquid, liquefied gas, natural gas, gas and low temperature fluid. In the foreign liquefied petroleum gas, refined oil and light crude oil transfer and gathering stations, the first and last stations of large crude oil pipeline are widely used for trade settlement. Turbine flowmeters in Europe and the United States are second only to orifice flowmeters for natural gas metering. The Netherlands alone has adopted more than 2600 gas turbine flowmeters of various sizes and pressures from 0.8 MPa to 6.5 MPa. They have become excellent natural gas flowmeters. Although the excellent metering characteristics of turbine Flowmeter are favored by people, it gives the impression that the moving parts are short in use and hesitant in selection. After people's unremitting efforts, it should be said that the situation has greatly improved. Turbine flowmeter as the most general flowmeter, its products have developed into multi-variety, full-series, multi-specification mass production scale.
In addition to the extensive use of the aforementioned industrial sectors, turbine flowmeters are also widely used in special sectors, such as scientific research and experiments, national defense science and technology, and metrology. The use of these fields avoids its weaknesses (not suitable for long-term continuous use) and gives full play to its characteristics (high precision, good repeatability, and can be used in conditions such as high pressure, high temperature, low temperature and micro In these fields, most of them are designed according to the special requirements of the subject, and they are special instruments without mass production.
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.
