Venturi Thermal Mass Flow Meter

Venturi Thermal Mass Flow Meter – Overview

This Thermal Mass Flow Meter features a Venturi structure, which guides airflow through a contraction-expansion zone to ensure steady and uniform flow across the sensing element. This flow conditioning structure helps to stabilise the airflow direction and velocity distribution, leading to improved measurement accuracy and consistent sensor output. Suitable for Compressed Air Systems, Pneumatic Systems, Dryers, Air Consumption Monitoring, and Pipeline Leak Monitoring.
