The RHE26 is a small footprint, low cost transmitter designed for rack, panel or DIN rail mounting in an indoor or enclosure environment. Multifunction capability provides real time flow, density and temperature indication. The RHE26 supports connection to any of the wide range of RHM series of precision mass flow sensors in both ordinary and hazardous areas. When used with the unique Rheonik Assurance Factor® advanced diagnostics package, the RHE26 provides deep insight into process and measurement conditions for precise control and improved end product quality.
