CDA flowmeter for compressors

1CDA flowmeter for compressorsProduct Introduction

UHMC Shanghai Youheng Measurement and Control Technology Co., Ltd.'s CDA flowmeter for compressors is an instrument that uses the principle of thermal conduction to measure fluid flow rate. The instrument uses the constant temperature difference method to accurately measure gas mass flow rate. Suitable for measuring the flow rate of various single component gas media, it is highly favored by both new and old customers due to its range comparison, good stability, easy installation, and high reliability

IICDA flowmeter for compressorsIntroduction to Principles

The compressed air flow meter UHMF product belongs to the hot wire mass flow meter. Simply put, it measures the flow rate through the heat exchange relationship between the fluid and the heat source, so it is also called a calorimeter flow meter. There are two sensors inside it, one measuring the fluid velocity and the other measuring the gas temperature change. During measurement, these two sensors will be placed in the measured gas at the same time. One sensor will be heated, and the other will be used to sense the measured gas. The increase in gas flow rate will carry more heat, causing the sensor temperature to decrease. By calculating the relationship between flow rate and temperature, the current flow rate value of the fluid can be obtained.
