Flow Sensors
CSM Correlation Sensor
Part No. CSM-V100Measurements starting at flow levels of 3 cm
Ultrasonic sensors for flow measurement with very high accuracy in slight to heavily polluted media. For installation on channel wall or channel bottom
Description
For high-accurate flow measurement by means of ultrasonic cross correlation method
- Infiltration measurement (extraneous water)
- Influent control
- Billing measurement places
- Discharge constructions
- Precipitation discharge measurements
The Mini sensor family provides the best possible sensors to detect lowest flow levels e.g. for infiltration measurement (extraneous water) or indirect discharge measurement.
The sensors use the proven ultrasonic cross correlation method patented by NIVUS. This method allows to detect and to indicate flow profiles starting at flow levels as low as a few centimeters.
Due to their shape the sensors are particularly suitable for small geometries and help to avoid backwater effects, the risk of build-up and clogging.
Typical applications for Mini sensors
- Measurement campaigns in channel networks
- Small WWTPs: intake and discharge
- Industrial wastewater networks
- Particularly suitable for channels featuring low flow levels
