Okay! A thermal mass flow sensor (commonly referred to as a Thermal Mass Flow Meter or Thermal Mass Flow Sensor) is an instrument that directly measures the mass flow rate of gases or liquids. Its core working principle is to use heat transfer characteristics to perceive fluid flow. The following is a detailed explanation of its key features and principles: Core principle (based on the law of thermal diffusion): Heating source: The sensor contains one (or more) heating elements inside. Temperature measurement: ..
Elveflow offers two types of flow rate sensors: one based on the thermal conductivity technology (Microfluidic Flow Sensor) and one based on the Coriolis principle (Bronkhorst Flow Sensor). Both sensors have pros and cons that have been summarized in the table below. This table ...
Thermal Mass Flow Sensor. The working mechanism of the sensor chip integrates heating elements and temperature sensitive elements. When the airflow passes through, the heat transfer path is changed, and the compensation power required for constant temperature difference control is proportional to the mass flow rate, thereby achieving high-sensitivity measurement of low flow rate and transient fluctuations. Typical devices and performance indicators MFS02 miniature thermal flow sensor: 0-1.5 m/s range in full bridge mode, 0-150 m/s range in CTA mode
Another form of thermal flow sensor locates multiple temperature sensors symmetrically about a heater (Kimet al., 2003, 2004; Ohnsteinet al., 1990; Parket al., 2003; Tanet al., 2007). If there is no fluid flow, the heat transported to the temperature sensors is equal. With a fluid flow...
