The Hydreka Doppler Velocity Probe (DVP), distributed by Matchpoint, measures uni- or bi-directional flows in open channel applications, even in very shallow water. The unit is IP68 as well as ATEX and NEMA6 certified. With RS232 or RS485 Modbus communication and low power consumption, it can be connected to most logging devices or directly into a SCADA system. It measures both temperature and speed and has integrated sound correction for increased accuracy. It is compatible with MainFlo units when a complete system is required. 910/509-7225; www.matchpointinc.us.
