DN4 - DN200 Turbine Flow Meter IP65 Low Flow Rate Start LCD Display

DN4 - DN200 Turbine Flow Meter IP65 Low Flow Rate Start LCD Display​

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.

It is widely used in the sealed pipelines which doesn’t have corrosion function on SS 1Cr₁₈Ni₉Ti, 2Cr₁₃, corundum Al₂O₃ and cemented carbide and have no fiber, particle and so on. The liquid should be less than 5*10^-6m²/s with viscosity under working temperature, if the viscosity of the liquid is more than 5*10^-6m²/s, then the flow meter can be used after calibration. If it is equipped with other display devices with special functions, it can also do quantity control, excessive alarm and so on. It is really perfect in flow measurement and energy

conservation.

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, etc. It is widely used in the first and last stations of large crude oil pipelines for trade settlement in foreign transportation and gathering stations of LIQUEFIED petroleum gas, refined oil and light crude oil. In Europe and the United States, turbine flowmeters are second only to orifice flowmeters for natural gas metering. In the Netherlands alone, more than 2,600 turbine flowmeters of various sizes with pressure from 0.8MPa to 6.5MPa have been adopted in natural gas pipelines. They have become excellent natural gas flowmeters. Although the turbine flowmeter is favored by people for its excellent metering characteristics, it gives people the impression that it is made up of moving parts and has a short use period. Therefore, it is inevitable to hesitate when choosing it. After people's unremitting efforts, it should be said that the situation has greatly improved. Turbine flowmeter as the most common flowmeter, its products have developed a multi-variety, full series, multi-specification mass production scale.

Turbine flowmeter in addition to the industry a large number of applications, is widely used in some special department, such as scientific experiments, national defense science and technology, measurement unit, the use of these areas to avoid its weaknesses (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 flow conditions). In these fields, most of the structures are designed according to the special requirements of the tested objects. They are special instruments and are not mass-produced.
