Supply LWQ gas turbine flowmeter LWQ-250 gas turbine flowmeter 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、 Technical parameters:

　　Measurement medium: gas

　　Range: Standard Range: 2.5-4000m3/h Extended Range: 4-6500m3/h

　　Output signals: pulse signal, 4-20mA current signal, control signal

　　Quality assurance: The company strictly implements relevant national warranty regulations, and the product is guaranteed for one year.

　　After sales service: The manufacturer provides shipping and after-sales service.

　　4、 Installation:

　　The on-site installation of flow meters must comply with GB3836. Part 15 of the Electrical Installation for Explosive Gas Environments (15-2000k): Electrical Installation in Hazardous Areas (Excluding Mining Explosions);

　　When installing the flowmeter, it is strictly prohibited to directly weld at its inlet and outlet flanges to avoid burning out the internal parts of the flowmeter;

　　When installing the flowmeter outdoors, there should be a cover on the upper part to prevent rainwater from entering and direct sunlight from affecting the service life of the flowmeter;

　　The flowmeter can be installed horizontally or vertically, and the direction of fluid flow should be consistent with the direction indicated on the casing. A straight pipe section with a diameter of 2DN should be ensured upstream of the flowmeter;

　　In order not to affect the normal transportation of fluids, a bypass pipeline must be installed, and the bypass pipeline valve must be closed during normal use.
