FTWM-2800No-C micro liquid mass flow meter
Designed for needshigh accuracyDesigned for flow measurement
FTWM-2800No-C micro liquid mass flow meter uses the principle of capillary heat transfer temperature difference calorimetry to measure liquid mass flow (without temperature and pressure compensation).Specifically designed for flow measurement of low-speed airflow in tiny liquid pipelines of DN1-8mm., with high measurement accuracy, good repeatability, fast response, soft start, stability and reliability, and easy installation.Features such as movable parts in the pipe, minimal pressure loss, product with display (optional) and control valve (optional), easy to observe.
FTWM-2800No-C micro liquid mass flow meter based onThe capillary heat transfer temperature difference calorimetry principle measures liquid mass flow (without temperature and pressure compensation). The flow signal measured by the sensor heating bridge is sent to the amplifier for amplification. The amplified flow detection voltage is compared with the set voltage, and then the difference signal is amplified to control the regulating valve. The flow rate flowing through the channel is controlled in a closed loop to make it equal to the set value. The flow divider determines the flow rate of the main channel.
