Page 3: Introduction
BB2 control box. 4. Measuring principle The FLX uses a pressure sensor to measure flow as a function of the level of the liquid in open channels. Different types of standardized weirs or flumes are used to achieve measurable rates of flow. -
Page 4: Unpacking The Sensor
Damages If damages occurred during shipment, immediately contact UPS or other truck line as well as your Cerlic representative. The shipment can be returned only after contact has been made with Cerlic. Packaging The original packaging is designed to protect the equipment and should be used for storage or if the goods must be returned. -
Page 5: Mounting
It is important that the sensor, once it has been removed, is re-positioned at the right height. An adjustable slide rail mounting is available as an option. In strong current, hydrodynamic effects may influence the measurement; contact Cerlic service for advice on current protection if problems occur. -
Page 6: Mounting A Sensor In A Weir
Mounting a Sensor in a Weir In a weir, the sensor should be placed at 4 times the maximum measuring height upstream from the overflow edge. If possible, measuring in a measuring well is preferably. However, this is not strictly necessary since the sensor ends up so far from the overflow that its interference with the flow profile is negligible. -
Page 7: Starting Up
If the sensor is held vertically in the air the level shall read zero (or close to zero). The FLX is pre-set at the factory, but sometimes the zero point still needs adjustment. (Refer “Adjusting the zero point”). NOTE, if an offset is entered in the sensors setting menu, the level shows the value of the offset instead of zero. -
Page 8: Maintenance
All sensors age, which eventually leads to inaccurate measurements. Check the sensor's zero point about once every six months by lifting the sensor into the air and observing the level the FLX registers. The level is shown in the sensors info display (opened by simultaneously pressing and ENTER). -

Page 11: Level Measurement
Level measurement FLX can be configured for level measurement by selecting the unit ”mm”or”inch” in the sensors settings menu. Type of flume, flume parameters and number of flumes selected are ignored. Preset, pulse relay and totalizer does not work for level measurement. -

Page 17: Calibration
Zero calibration The FLX has a zero point calibration function, which is based on lifting the sensor into the air (zero pressure) and pressing a key. The BB2 registers the signal from the sensor and bases all subsequent measuring on that signal level. -
