Sell LWQ gas turbine flowmeter LWQ-125 gas turbine flowmeter for direct sales

Description :

　　1. Overview:

　　The LWQ gas turbine flowmeter is a velocity based flow meter that accurately measures gas flow rate. It has the advantages of simple and lightweight structure, high measurement accuracy, good repeatability, wide measurement range, and easy installation and maintenance.

　　2、 Main features:

　　Adopting precision bearings specifically designed for imported instruments, with high accuracy and good stability, it can be used without refueling for five years under normal conditions.

　　The carefully designed flow channel structure avoids the flow of air between the bearings and improves the medium adaptability of the turbine flowmeter.

　　The unique reverse thrust structure and sealing structure design ensure the long-term reliable operation of the bearing.

　　The flowmeter head can rotate 180 °, making installation and use simple and convenient.

　　Design a rectifier with excellent rectification performance, with very low requirements for the front and rear straight pipe sections (front ≥ 2DN, rear ≥ 1DN).

　　Adopting low-power high-tech, it can work with both internal and external power sources, and the internal battery can work continuously for more than five years.

　　By using RS485 interface to form a network communication system, automated management can be easily achieved.

　　3、 Category:

　　1. Gas turbine flow transmitter

　　The gas turbine flow transmitter consists of a turbine flow sensor and an amplification circuit or transmission device, which converts fluid flow into electrical pulse signals or current signals for output, and does not have a display mechanism.

　　2. Ordinary gas turbine flowmeter

　　Ordinary gas turbine flow meters are divided into two types: mechanical and electronic. The former consists of a gas turbine flow sensor and a mechanical counter, while the latter consists of a gas turbine flow sensor and a flow integrator, but neither of them has pressure and temperature compensation function, only measuring the working condition volume flow of the gas.

　　3. Temperature pressure compensation type gas turbine flowmeter

　　The temperature pressure compensation type gas turbine flowmeter considers the compressibility of gas, so it adds pressure sensors and temperature sensors. Therefore, it consists of four parts: turbine flow sensor, pressure sensor, temperature sensor, and temperature pressure compensation instrument. It converts the working condition volume flow rate into standard volume flow rate and directly measures the standard volume flow rate and cumulative flow rate.

　　4、 Maintenance:

　　1. Before putting the flowmeter into operation, it is necessary to set the instrument coefficient and carefully check to ensure that the flowmeter wiring is correct and well grounded before power can be transmitted.

　　2. Regularly clean, inspect, and recalibrate the flowmeter. Flow meters with lubricating oil or cleaning solution injection ports should be regularly filled with lubricating oil or cleaning solution according to the instructions to maintain the good operation of the impeller.

　　3. Monitor and display the condition of the instrument, and promptly check if there are any abnormalities in the instrument readings.

　　4. Keep the filter unobstructed. The filter is blocked by impurities, which can be judged by the increase in the pressure gauge reading difference at its inlet and outlet. If there is a blockage, it should be promptly eliminated, otherwise the flow rate will be severely reduced.

　　5. For high flow trade settlement measurement, in order to ensure the accuracy of the flowmeter, it must be regularly calibrated. Online verification equipment or mobile verification devices should be equipped on site. Although the one-time investment is relatively large, it is worth considering the long-term economic benefits.
