Insertion Thermal Mass Flow Meter – Overview

This one-of-a-kind mass flow meter is popular in industrial applications. It can be used for low-flow measurement. It features no moving parts, a nearly unobstructed flow path, and retains accuracy over a wide range of flow rates. It requires no temperature or pressure corrections. Straight pipe runs can be reduced by using dual-plate flow conditioning elements.  Installation is simple with minimal pipe intrusions. Easy to use. Suitable for all kinds of single or mixed gas flow measurement and gas leak detection. Sized from DN40~DN2000mm. It supports multiple communication methods, such as RS485 communication, and MODBUS protocol.
