HGDU800-P Portable Serials

HGDU800 series Flow Meter consists of flow calculator, and the integrated DOF 6526 transducer to measure velocity and level at the same time.

The flow calculator can display the velocity, level, flow rate and flow totalizer. It also can be available with 4-20mA, RS232, RS485 (Modbus) /GPRS and SD card logger outputs. It can record data of flow rate and total flow with a SD card up to 16GB.

The flow calculator can calculate the cross-sectional area of partially filled pipe, open channel stream or river, for stream or river, it can input up to 20 coordinate points describing the river’s shape of cross section. It is suitable for various applications.

The DOF6526 Velocity and Level Transducer is a unique combination of water velocity, depth and temperature instruments integrated with a solid state logger. It is a new generation of intelligent flow measurement systems.

Rechargeable battery can work up to 40 hours.
Measure flow in partially filled pipes and open channels.
No flume or weir required.
Display the velocity, level, flow rate and flow totalizer.
4-20mA, RS485 (Modbus) /GPRS outputs are available.
16GB SD card data logger can be optional.
20 coordinate points to describe the river’s shape of cross section.
