Explosion proof DN80 gas turbine flowmeter

Description :

　　Explosion proof DN80 gas turbine flowmeter

　　The excellent low-pressure and high-pressure metering performance, multiple signal output modes, and low sensitivity to fluid disturbances of this product make it a special commercial trade metering instrument that can accurately measure gas accumulation.

　　1、 Characteristics:

　　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.

　　3、 Installation form:

　　1. The internal structure should use a reverse thrust turbine flowmeter. Because the reverse thrust structure can keep the impeller in a floating state within a certain flow range, there are no contact points in the axial direction, and there is no end face friction and wear, which can extend the service life of the bearing.

　　2. According to the selection of pipeline connection methods, flow meters can be installed horizontally and vertically. Horizontal installation and pipeline connection methods include flange connection, threaded connection, and clamp connection. Select flange connection for medium caliber; Use threaded connections for small-diameter and high-pressure pipelines; Clamp on connections are only suitable for low-pressure small and medium-sized pipe diameters; Vertical installation only has threaded connections.

　　3. Select based on environmental conditions, taking into account the effects of temperature and humidity. Natural gas metering should choose intrinsically safe explosion-proof turbine flow meters.
