Rechargeable Battery Flow Measurement Devices IP68

DOF6000-P Portable Doppler Open Channel Flow Meter

The Ultraflow QSD 6537 Sensor is used to measure water velocity, depth, and conductivity of water flowing in rivers, streams, open channels and pipes. When used with a companion Lanry DOF6000 Calculator, flow rate and total flow can also be calculated.

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

The 6537 Instrument has a 4 electrodes conductivity instrument (EC) included to measure the quality of the water, with four electrodes exposed to the water at the top of the instrument. Water quality is measured on an ongoing basis and this parameter can be recorded along with velocity and depth to better analyse the nature of the water in open channels and pipes.

Features:

• Rechargeable battery can work up to 50 hours.
• 20 coordinate points to describe cross section of the river’s shape.
• One instrument can measure the velocity, depth and conductivity simultaneously.
• Velocity Range : 0.02mm/s to 12m/s bi-directional, accuracy is 1%.
• Depth Range: 0 to 10m.
• Measure velocity in both forward flow and back flow.
• Depth is measured by both the pressure sensor and ultrasonic level sensor principles.
• With borometric and pressure compensation function.
• IP68 Epoxy-sealed body design, designed under water installation.
• RS485/MODBUS output, connect to computer directly.
