IP65 Thread Type Industrial Flow Meter Turbine Flow Transmitter
Simple Structure
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 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.
