Hot Water Turbine Flow Meter with LCD Display Battery Operated
Power Supply
1. Introduction
LWGYML series intelligent liquid turbine flowmeter is a new type of intelligent instrument, which is developed by using advanced ultra-low power consumption single chip microcomputer technology. It has the advantages of compact structure, intuitive and clear reading, high reliability, no interference from external power supply, lightning resistance and low cost.
2. Application
Turbine flowmeters are widely used in the following measurement
objects: petroleum, organic liquids, inorganic liquids, liquefied
gas, natural gas, coal gas and cryogenic fluids. It is widely used
in the transfer and gathering stations of foreign liquefied
petroleum gas, refined oil and light crude oil, and the first and
last stations of large crude oil pipelines for trade settlement. In
Europe and the United States, turbine flow meters are second only
to orifice flow meters for natural gas measurement. In the
Netherlands alone, more than 2,600 gas turbine flow meters of
various sizes and pressures ranging from 0.8 MPa to 6.5 MPa are
used in natural gas pipelines. Has become an excellent natural gas
flow meter. Although the excellent metering characteristics of
turbine flowmeters are favored by people, they give people the
impression that they are made of movable parts and have a short
service life. They can't help but hesitate when choosing them.
After people's unremitting efforts, it should be said that the
situation has improved greatly. Turbine flowmeter, as the most
common flowmeter, has developed into a multi-variety, full-series,
and multi-specification mass production scale. In addition to a
large number of applications in the aforementioned industrial
sectors, turbine flowmeters are also widely used in some special
sectors, such as scientific research, national defense science and
technology, and measurement sectors. The use of these fields just
avoids its weaknesses (not suitable for long-term continuous use)
and gives full play to Its characteristics (high precision, good
repeatability, 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 objects. They are special instruments and are not
mass-produced.
3. 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.
