Water monitoring: Sediment load
OTE-SEDA
Measurement
Thanks to using the OLPAS ultrasound measurement technology, the sensor is much less negatively impacted by fouling on the sensor head.
This results in maintenance intervals that are much longer compared to optical sensors.
There is no need for wipers.
Advantages
The ultrasound OLPAS Technology provides a robust measurement that is not prone to changing water colour or other optical changes that are not relevant for the actual SSC (Suspended Sediment Concentration)
Olpas sensors measure through fouling, requiring much less maintenance
and no need for automated mechanical cleaning (no wipers, no pressured air)
Due to the longer maintenance window, Olpas sensors can be installed on hard to reach locations (eg. in canals or in open nature), while still providing an economical measurement
Installation
The Olpas Tentacle is designed to operate fully or partially submerged in water at all times. Contact with water on the ultrasonic window is necessary to perform a measurement. maintenance interval due to strong adhesion of dirt residues.
Fixed mounting
The fixed mounting of the sensor is done using two hanging brackets (M10).
Suspension
A flexible installation can be achieved by suspending the sensor from the provided bracket using a stainless steel chain. This can be done either as a free-hanging installation (no restriction on lateral movement of the sensor) or by using a standpipe (restricting the lateral freedom of the sensor).
Both solutions are ideal for easily removing the sensor for routine or preventive maintenance.
Water Level
The Olpas Tentacle is designed to operate fully or partially submerged in water at all times. Contact with water on the ultrasonic window is necessary to perform a measurement.
Temporary drying
Temporary drying of the sensor will not cause damage, and the sensor will automatically resume operation upon contact with water. However, frequent drying of the ultrasonic window will shorten the maintenance interval due to strong adhesion of dirt residues.
