Gas vortex precessionflowmeter

Introduction

The vortex flowmeter integrates flow acquisition, temperature and pressure detection functions, and can automatically compensate for temperature, pressure and compression factor. It is widely used in the measurement of conventional gases such as natural gas, nitrogen, hydrogen, compressed air, coal gasification, liquefied gas, and light hydrocarbon gas. The vortex flowmeter adopts advanced microprocessing technology, with high reliability and high calculation accuracy. It has excellent flow monitoring performance in online measurement of natural gas pipelines, can measure gas flow under low pressure, has a wide flow range, multi-signal output, and low interference sensitivity. It is simple to operate and maintain, and easy to install and use.

Advantages
Precession Vortex Flowmeter Advantages

It can display temperature, pressure, instantaneous flow and cumulative total on site, and can be transmitted remotely as needed;
The process installation conditions are not harsh, and the upstream and downstream straight pipe sections of the instrument can be greatly shortened compared to the orifice flowmeter;
The system measurement accuracy can meet the trade measurement requirements (≤2%);
The flow measurement range is wide (qmax/qmin=15~20), and it can also work effectively in small flow areas that the orifice flowmeter cannot measure;
Small size, light weight, and offline calibration is more convenient;
The instrument has no moving parts and will not produce mechanical wear when used for general measurements;
Reliable anti-theft function, with password protection to prevent parameters from being changed;
Instrument management personnel do not need professional training, flow, pressure, temperature The measurement parameters such as temperature and humidity can be read directly from the meter head without conversion;
The unique time display and real-time data storage function ensure that the internal data will not be lost under any circumstances and can be permanently stored;
The whole machine has extremely low power consumption and can be powered by the internal battery for a long time. It is an ideal field display instrument without external power supply;
The new signal processing amplifier and unique filtering technology are used to effectively eliminate the interference signals generated by pressure fluctuations, pipeline vibrations, etc., greatly improving the anti-interference ability of the flow meter, so that small flow also has excellent stability;
It has two-wire and three-wire 4~20mA standard current signal output, pulse output and RS485 interface;
It realizes mechatronics, built-in pressure, temperature, flow sensors, and a variety of compensation methods for users to choose. It has high safety performance, compact structure, beautiful appearance, and no manual supervision is required during daily metering.
