It is distinguished between the following level sensors:
1 Air-ultrasonic type >OCL< or >DSM< by NIVUS
2 Water-ultrasonic integrated into flow velocity sensor,
types: POA-V1H1 or CS2-V2H1
3 2-wire probe EX, e.g. types: NMC0 or HSB0NBP
4 Fixed value for permanently full filled applications or for testing purposes
5 Pressure measurement cell integrated into flow velocity sensor,
types: POA-V1D0 or CS2-V2D0
6 2-wire probe, e.g. types NM5-3101 or HSB0HG, i-Serie Ex
Fig. 9-32 Determination of level sensor type
Note
When using combi sensors featuring multiple level measurements (water-
ultrasound and pressure measurement cell, e.g. type POA-V1U1 or CS2-
V2U1) it is necessary to select both level measurements in the selection
menu.
Sensor type 1: Air-ultrasonic (Air-US NIVUS)
Level measurement by using active air-ultrasonic sensor from top down. May be
combined with the flow velocity sensor
This sensor can be used to detect low flow levels, e.g. to measure nightly dis-
charge.
The sensor must be installed exactly in the centre of the channel vertex, (± 2°)
parallel to the water surface.
An air-ultrasonic sensor type OCL or DSM is required!
