Page 9: General View Of The Lowtus Sensor
The PREMIUM version is described below with its automatic cleaning system built into the removable lid. In this version, a specific cable transfers energy from the main part of the LowTuS device to a motor in the lid to generate a cleaning process using a rotating arm with a rubber blade. - Page 10 The turbidity equivalent value of the tool is factory defined for the LowTuS device. Consequently, the tool is compatible with a single device. This tool contains two holes which combined with the pin fixed in the upper part of the measuring cell allow for two positions of use.

Page 11: Measurement Chain Description And Measuring Principle
The measurement principle is based on measuring InfraRed light diffusion at 90° (ISO 7027) and enables continuous monitoring of turbidity across low measurement ranges. The LowTuS device is an open protocol RS485 Modbus slave. It delivers temperature and turbidity values to a master. This master could be either a local display-controller-transmitter or a remote monitoring system. -

Page 19: Maintenance/Cleaning Sequence
8. MAINTENANCE/CLEANING SEQUENCE 8.1 Maintenance steps - Stop the wiper cleaning cycle (turn off the LowTuS device). - Stop the fluid supply to the cell. If the drain valve is not connected to a drain pipe, put a tank under the flow cell. - Page 20 LowTuS After internal cleaning or calibration process, check the O-ring is in good condition, Close the flow cell, place the lid on the top of the flow cell. The right position is obtained when the pin is in the small hole.

NOTE: The LowTuS device description contains “WIPER” if it is a premium version with an autocleaning system. - 21 -... - Page 22 LowTuS SENSOR DETAIL This window contains 4 main aspects: Description and versions, Network address selection, User settings button, Manual measurement window with description parameters, units, instantaneous values, measurement status. It enables occasional measurement of all available parameters during the device set-up phase.
- Page 23 Furthermore, the user can, in maintenance sequence, freeze the cleaning periodicity, or manually generate one cleaning action. During the life of the LowTuS device (premium version), the cleaning system’s rubber blade must be changed. Simultaneously, the user must reset the cleaning counter.

Page 24: Calibration
LowTuS The operator can select parameters between the available list and load this selection in a named CSV file. 9.3 Calibration 9.3.1 General The calibration screen can be accessed from the main screen when one or more sensors are selected. Only selected sensors will be calibrated. -
Page 25: Parameter Selection
LowTuS 9.3.2 Parameter selection application automatically selects the common parameters from all the sensors. Multiple calibration can only calibrate one parameter at a time. The operator's name has to be filled in before running the calibration. a. Fluid temperature parameter Two-step sequence i.e. - Page 26 LowTuS Step 1: Offset Subject the unit to water circulation in stabilized low temperature conditions, fluid at T1. master sends requests repeated measurements until sufficiently stable measurement is obtained, Write the temperature value T1 (°C), delivered by the reference equipment, in the "Reference value"...
- Page 27 LowTuS b. Turbidity parameter Complete calibration is performed with a static solution of formazine. 1. Close the taps to isolate the cell from the fluid circuit 2. Open the lid and pour 80ml to 100ml of clear water or formazine solution into the cell.
- Page 28 LowTuS Step 1: Offset Subject the unit to demineralized water. When the measurement is stabilized, write the turbidty value in the “reference value” box Step 2: Gradient Wipe the measuring cell with a clean cloth before adding a formazin solution.
