Installation Guide K0J00025-EN-A03 1. Introduction Some Ijinus loggers are equipped with a water height measurement by aerial ultrasonic, with automatic measurement cycle changes depending on thresholds, flow rate transformation through conversion tables,… . Some sensors are equipped with connectors for coupling with an overflow detector or to control water sampler.
Installation Guide K0J00025-EN-A03 3. Equipment (4 configuration examples) a. Temporary Installation The sensor is autonomous and battery powered (lithium battery), it measures water level by air ultrasonic waves. It has internal logger and data can be retrieved on-site (by radio using the programming kit : Wiji). Ultrasonic sensor Lithium battery Water sampler cable Programming kit Overflow detector Fixations: Bracket, fixations either with single or double metal plate with bracket b.
Installation Guide K0J00025-EN-A03 Sensor integrating a logger, communication modem and its deported antenna c. Permanent installation of several level sensors and a logger (Permanent diagnosis or CSO equipment): The level sensor that is battery powered send data locally by short range radio and the logger retrieve the data of the level sensors or others and send them by cellular communication. Data logger as a radio/3G access point d. Other configurations.
Installation Guide K0J00025-EN-A03 4. Quick configuration with the software Avelour We will show here the classical version of the system programing, level measurement and data sending by 2G, 3G, LTE or NB-IoT. a. Necessary equipment - The Avelour software - Programing Wiji kit or Wiji key Avelour Wiji kit Wiji key a.
Installation Guide K0J00025-EN-A03 b. First step : Run Avelour and connect to the sensor to configure After connection of the Wiji kit (or the Wiji key) on your computer USB port, run the Avelour software. Click on the button “Connect to a wireless device” then the logger will be directly visible by its part number (SN) without the need to activate anything else (ex: IJA0101-0000 3559). Locate the sensor's serial number (SN) on the sensor label and click "OK".
Installation Guide K0J00025-EN-A03 When the sensors is ready, Avelour will look like bellow: d. Third step : Configuration of Measurement part This part is divided in several paragraphs. Each part will be detailed. General informations This part is useful to describe the measurement point. The most important information would be the name that will help you to find your sensor at a future connection.
Installation Guide K0J00025-EN-A03 Choice of the measurement period In this new menu, select the measurement frequency (in this example every 15min). To the right of the measure period selector, 2 little icons allowing a deferred programming according to the time period and day of the week you can choose from. So far the sensor is not calibrated. Calibration of the water height After clicking the calibration button the bellow windows appears: IJINUS – 25 ZA de Kervidanou 3 – 29300 MELLAC – FRANCE - www.
Installation Guide K0J00025-EN-A03 It is difficult to establish rules but globally 3 cases may arise: CASE 1 : Ideal case: unique echo (test in lab or if the sensor front flat water surface for example) A simple calibration would be possible. CASE 2 : Case of a classic manhole with an invert channel in the bottom. The figure bellow shows two echoes (the invert and the water). A calibration in advanced mode will be possible.
Installation Guide K0J00025-EN-A03 CASE 3 : Complex case The presence of many echoes make difficult the calibration the easiest way. A priority should be to move the sensor if possible otherwise go to the expert mode. (Only for experienced users). Calibration of the sensor Case N°1 (Ideal) The first case presenting only one echo, you only need to adjust the water height H or the maximal distance between the sensor and the bottom Z and relaunch a measure.
Installation Guide K0J00025-EN-A03 Calibration of the sensor Case N°2 (Classic example of a manhole with an invert channel) In case no. 2, with an echo having several peaks, the software indicates the presence of "critical" obstacles that can disturb the measurement if no modification is done to the calibration. These critical obstacles appear in red on the graph, while the echo reported by the sensor as the measurement is shown in green. The power indicator (yellow line) is always present.
Installation Guide K0J00025-EN-A03 - This advanced mode also allows to create an “obstacle filter” that consist in masking obstacles echoes that disturb the measure like in the case of invert, ladder rungs present in the field of view of the sensor. After clicking on “Create an obstacle filter”, you need to choose with the tick box the obstacle matching the wanted measure (water height), press “Create”.
Installation Guide K0J00025-EN-A03 Finally, you need to launch a new measure to check the relevance of the result so: - The green line position used for the measure, - Values of the echo slightly higher than the power indicator, - and validate by pressing the Apply button Calibration of the sensor Case N°3 (complex) – Expert mode The expert mode is to be used only in complex cases and need user experience and knowledge of ultrasonic measure data processing.
Installation Guide K0J00025-EN-A03 Change measure period on height threshold For some sensors, you can have two different time of data acquisition depending on water height measures. For example, you can measure every hour when the level is low and accelerate to 2 minutes when level goes above a threshold. This measurement period acceleration can be set to some time slots, following an exceedance of level (with or without hysteresis) and with the choice of a minimum time before deceleration.
