Supply low-priced LWQ-100 gas turbine flowmeter

Description :

　　LWQ-100 gas turbine flowmeter

　　This product is widely used in various industries such as petroleum, chemical, metallurgy, aviation, and scientific research. Due to its high instrument accuracy and good repeatability, it is suitable for trade measurement and industrial process testing.

　　1. Product Features:

　　Adopting a new type of sensor, it has low starting flow rate, small pressure loss, good anti vibration and anti pulsating flow performance, is not easy to corrode, has good reliability, and has a long service life.

　　Adopting a new type of microprocessor and high-performance integrated chips, it has high computational accuracy, powerful overall functions, and superior performance.

　　Adopting advanced low-power high-tech, the whole machine has low power consumption. It can operate on both internal battery power for a long time and external power supply.

　　According to the flow frequency signal, the instrument coefficient can be automatically linearly corrected in eight segments, which can improve the calculation accuracy of the instrument according to user needs.

　　Adopting EEPROM data storage technology, it has the function of storing and querying historical data, and three historical data recording methods are available for users to choose from.

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

　　High precision, generally up to ± 1.5% R and ± 1.0% R.

　　Good repeatability, short-term repeatability can reach 0.05% R~0.2% R. It is precisely because of its good repeatability that flow meters are preferred in trade settlement.

　　3、 Installation:

　　1. The flowmeter must be installed horizontally on the pipeline (with the pipeline tilted within 5 degrees), and the axis of the flowmeter should be concentric with the axis of the pipeline during installation, with the flow direction consistent.

　　2. The upstream pipeline length of the flowmeter should have an equal diameter straight pipe section of not less than 2D. If the installation site permits, it is recommended that the upstream straight pipe section be 20D and the downstream be 5D.

　　3. Requirements for piping: The inner diameter of the upstream and downstream piping at the flowmeter installation point should be the same as the inner diameter of the flowmeter.

　　4. Requirements for bypass pipe: In order to ensure that the maintenance of the flowmeter does not affect the normal use of the medium, shut-off valves (globe valves) should be installed on the front and rear pipelines of the flowmeter, and a bypass pipe should also be set up. The flow control valve should be installed downstream of the flowmeter. When using the flowmeter, the upstream shut-off valve must be fully opened to avoid unstable flow of fluid in the upstream section.

　　5. Requirements for external environment: Flow meters are better installed indoors. If they must be installed outdoors, they must be protected from sunlight and rain Lightning protection measures should be taken to avoid affecting the service life.

　　6. Requirements for impurities in the medium: In order to ensure the service life of the flowmeter, a filter should be installed before the straight pipe section of the flowmeter.
