Rheonik RHE 28 Universal Mount Flow Transmitter

Description

The RHE28 is an advanced function transmitter in a rugged epoxy coated enclosure designed for field mounting. With enclosure ratings up to IP67, the RHE28 has the flexibility to be installed in both ordinary and hazardous areas (Zone 2). Features such as API Standard Volume correction and Net Oil calculation are available. With highly accurate measurement performance and extreme capabilities, Rheonik meters are a natural choice for many applications and quickly provide payback through improved product quality and greatly reduced maintenance. Whether used for transfer, batching, process feed or control, Rheonik meters can provide online flow and density measurement.
