Double Power System Turbine Flow Meter High Accuracy Strong Signal Resolution
1. Introduction
LWGYML series intelligent liquid turbine flow meter is a new type of intelligent instrument with integrated turbine flow sensor and display product calculation developed by advanced ultra-low power single-chip microcomputer technology, which has obvious advantages such as compact mechanism, clear reading, high reliability, undisturbed by external power supply, lightning resistance and low cost.
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: oil, organic liquid, inorganic liquid, liquefied gas,
natural gas, gas and cryogenic fluid and so on. It is widely used
for trade settlement at the transshipment and gathering stations of
liquefied petroleum gas, refined oil and light crude oil abroad,
and at the first and last stations of large crude oil pipelines. In
Europe and the United States, turbine Flowmeters are natural gas
meters second only to orifice Flowmeters. Only in the Netherlands,
more than 2600 gas turbine Flowmeters of various sizes and
pressures from 0.8MPa to 6.5MPa have been used in natural gas
pipelines. They have become excellent natural gas Flowmeters.
Although the excellent metering characteristics of turbine
Flowmeter are favored by people, it gives people the impression
that it is made up of moving parts with short service life and
hesitation in selection. Through people's unremitting efforts, it
should be said that the situation has greatly improved.Turbine
Flowmeter as the most general Flowmeter, its products have been
developed into a multi-variety, full-series, multi-specification
mass production scale.
In addition to the extensive application of the turbine Flowmeter
in the above-mentioned industrial departments, it has also been
widely used in some special departments, such as scientific
research and experiments, national defense science and technology,
and metrology departments. The use of these fields just avoids its
weakness (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 micro-flow conditions). In these fields, most of them carry out
special structural design according to the special requirements of
the tested object, and they are special instruments that do not
carry out mass production.
