In a channel, a weir causes a variation in water level upstream which is directly proportional to the variation in flow rate. Level measurement can be performed with different systems; we offer the “float system”.
This is in particular of a linear extensometer sensor, associated with a float carrying on the top end of a bar, with this integral, which serves as the mobile element of the extensometer
In this case it is composed of a linear extensometer sensor linked to a float which serves as the mobile element of the extensometer?
Each movement of the float, which freely follows the water level, is transferred communicated to the sensor that detects the float
The system for the measurement of dam leakages, is composed of:
- Weir of known overflow section (triangular, rectangular or other)
- LVDT linear transducer (or other on request)
- Application and support device
||LVDT , potentiometer, magnetostrictive
||-55 ÷ 150°C
||4-20mA (directly or using a converter signal)
|Precision obtainable ( sensor / floating)
