A rotameter, also known as a float flowmeter, is a conical tube that is gradually enlarged from bottom to top by two components; and a rotor that is placed in the conical tube and is free to move down the centerline of the tube. It is a flowmeter that calculates a flowmeter by an area variable. The rotor flowmeter is a glass and a metal rotor flowmeter. The most commonly used in the industry are metal rotameters, such as the fire industry, thermoelectrics, and metallurgical pharmacies . Then, for corrosive fluids, glass materials are usually used, but rotameters made of precious materials such as glass materials and all-titanium materials have become mainstream. Rotor flowmeters are used when there is a need for rapid flow in petroleum, chemical, textile printing and dyeing .
The Rotameter produced by Nanjing Dasman Machinery Co., Ltd. has achieved good results in professional testing and long-term stability testing, because Nanjing Dasman Machinery Co., Ltd. carefully studied the work of the rotameter when designing. The principle is actually very simple, that is, when the fluid to be measured flows through the annular section between the rotor and the wall of the conical tube, the fluid will flow out from the upper end. There is also the problem of reading the rotor flowmeter produced by Nanjing Dasman Machinery Co., Ltd. In fact, the data read on the rotameter is instantaneous flow, either volume flow or mass flow. For example, if it is mass flow, you must first convert the mass flow into volume flow (in m3/s ) in order to get the specific flow. After the conversion, you can use the volume flow ratio according to the size of the rotor flowmeter. The result of the last cross-sectional area is that you want to get specific traffic.
