Talking about gas rotor flowmeter
2012-1-17 10:02:54

采用可变面积式测量原理,适用于测量液体,气体。 The gas rotor flowmeter uses the variable area measurement principle, which is suitable for measuring liquids and gases. All-metal structure, including indication type, electric remote transmission type, corrosion resistance type, high voltage type, jacket type, explosion-proof type. With 0-10mA,

4-20mA standard analog signal output and field indication. Accumulation, digital communication, on-site modification of measurement parameters, different power supply functions, with magnetic filters and special specifications. Widely used in petroleum, chemical,

Power generation, pharmaceuticals, food, water treatment, etc. Complex, harsh environmental conditions, and various media conditions during flow measurement.

浮子在测量管中,随着流量的变化,将浮子向上移动,在某一位置浮子所受的浮力与浮子重力达到平衡。 The gas rotor flowmeter float is in the measuring tube. As the flow rate changes, the float is moved upwards, and the buoyancy received by the float at a certain position reaches a balance with the gravity of the float. At this time, the distance between the float and the orifice plate (or cone tube)

The circulating annulus area remains constant. The area of the ring gap is proportional to the rising height of the float, that is, the position where the float rises in the measuring tube represents the magnitude of the flow. The position of the change float is transmitted by the internal magnet to the external indicator, so that

The indicator correctly indicates the flow value at this time. This makes the indicator housing not in direct contact with the measuring tube, so even if a limit switch or transmitter is installed, the instrument can be used under high temperature and high pressure working conditions.

是工业自动化过程控制中常用的一种变面积流量测量仪表。 Gas rotor flowmeter is a variable area flow measurement instrument commonly used in industrial automation process control. It has the characteristics of small size, large detection range and convenient use. It can be used to measure liquids, gases, and

The flow of steam is particularly suitable for the measurement of medium flow with low flow rate and small flow.
