1. Description

An open channel flow meter for efficient management of open sweage, industrial water treatment, and irrigation water in the open channel


2. Measurement Principle

First, mean velocities at various depths are measured using multiple sensors mounted on staffs that are located in 450 angle to each other at both sides of the channel. Then, the fluid level is measured using the sonic level meter or the ultrasonic depth meter that is separately installed. Finally, the flow volume is calculated from the velocities and the level.


3. Featurese and Applications

a. Flow measurement in the open irrigation waterway
Agricultural irrigation water discharge can be controlled for efficient water supply.

b. Flow measurement of tap water, sewage and industrial water
Water inflow and outflow can be controlled with accurate flow measurement in open channels.

c. Flow measurement in streams when there is a wide variation of flow with high velocity
Water can be controlled efficiently in the flood season with accurate flow measurement.

d. Flow measurement for backward flow
Backward flow can be measured efficiently in the lower stream leading to the sea with very high tide. Also backward flow can be measured efficiently in the upper stream leading to the dam and reservoir with high level.

e. Flow measurement at floodgate
Loss of water between the upper stream and the lower stream due to evaporation, leakage into the soil or volume changes due to the addition of underground water to the ground water from the bed and the banks can be measured efficiently. The inflow and outflow at the dam and reservoir can be measured.

f. Warranty
One year full labor and parts.

g. Price
Very competitive
