Overview
Enviro Testers small fLow range mass flow meters are made with MEMS sensing technology. It applies for clean and dry gas metering and control. The meter is designed with the structure of a rotameter but with the full capability of a digital gas mass flow metrology and LED display. Both instant and accumulated flow rate can be read and displayed. The front buttons let users access and adjust the parameters as well as stored data. The standard RS485 Modbus enables remote access and integration.
