Multi-orifice balance flow meters measure steam flow

Project Overview

Porous balance flow meters are differential pressure flow meters. The sensor is a multi-hole disc throttling rectifier, which is installed on the cross section of the pipe. The size and distribution of each hole is customized based on established formulas and test data. , called a function hole. When the fluid passes through the function hole of the disk, the fluid will be balanced and rectified, and the vortex will be minimized, forming an approximately ideal fluid. Through the pressure sensing device, a stable differential pressure signal can be obtained, and the volume flow rate, mass flow.

Operation steps when measuring steam flow with porous balance flowmeter

When measuring steam flow, high-temperature steam should be prevented from directly entering the differential pressure meter. Generally, a condenser is installed at the pressure port of the sensor. The function of the condenser is to condense the measured steam and then enter the differential pressure gauge through the pressure tube. The operation is as follows: when the liquid temperature in the condenser drops below 80°C, first open the balance valve in the three-valve group, then slightly open the positive and negative pressure valves on the three-valve group, and discharge the gas from the exhaust needle on the differential pressure gauge. Drain all the air in the valve, then close the exhaust needle valve, and then close the balance valve on the three-valve group. Once the transmitter system is zeroed, the instrument can be put into normal operation. (Note: Non-professionals are not allowed to operate.)

Supmea Measurement and Control has been engaged in the R&D and production of flow meters for many years. In addition to measuring steam media, its HSP series porous balance flow meters also support liquid air. It can measure liquid nitrogen, liquid oxygen, liquid argon, liquefied ethylene, liquid hydrogen, liquid chlorine, vapor-liquid two-phase, bidirectional flow and other media. It has a wide range of use and good measurement results.
