The E+H Proline Prosonic Flow 93C ultrasonic flow meter provides inline volume flow measurement of process water, saltwater, demineralized water, drinking water and wastewater. The meter's measuring system consists of a combination of a Prosonic Flow 93 transmitter in wall mounting housing and an optimized version of the Prosonic Flow W insertion sensor. The measuring principle is independent of pressure, density, temperature, conductivity and viscosity. The Prosonic Flow 93C inline combines the fundamental, high accuracy of an ultrasonic flow measuring system and the possibility of a traceable calibration.

The Prosonic Flow 93C is a dual path system with two pairs of insertion sensors, and the bidirectional flow measurement causes no pressure loss. In addition, the system provides high accuracy, short inlet run requirements, removal and replacement of sensor elements without process shutdown, and traceable calibration. The meter also features remote configuration using FieldCare software.
