4 - 20mA Turbine Flow Metre Digital Turbine Water Meter Easy Installation
1. Introduction
LWGYML series intelligent liquid turbine Flowmeter is a new type of intelligent instrument with the integration of turbine flow sensor and display accumulation developed by advanced ultra-low power consumption single-chip microcomputer technology. it has the advantages of compact mechanism, intuitive and clear reading, high reliability, no interference from external power supply, anti-lightning strike, low cost and so on.
Turbine flow meters are widely used in the following measurement objects: petroleum, organic liquid, inorganic liquid, liquefied gas, natural gas, gas and low temperature fluids. In foreign liquefied petroleum gas, refined oil and light crude oil and other transshipment and collection stations, large crude oil pipelines are used in large numbers for trade settlement. In Europe and the United States, turbine flow meters are second only to the perforated flow meters of natural gas meters, the Netherlands alone in the natural gas pipeline using more than 2,600 various sizes, pressure from 0.8MPa to 6.5MPa gas turbine flow meters, they have become excellent natural gas flow meters. Although the excellent measurement characteristics of turbine flow meters are favored by people, but give the impression that by the moving parts, the use of short, in the selection of inevitable, after people's unremitting efforts, it should be said that the situation has greatly improved. Turbine flow meter as the most common flow meter, its products have developed into a variety, full range, multi-size mass production scale.
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.
