    Before starting to work, you have to check the functioning and integrity of the system. § Check for visible defects on the WLR 8/15/30, this may or may not include any or all of the following mounting facilities, connectors and connections, mechanical parts, internal or external communication devices, power supplies or power supply lines, etc.

  • Page 6: Part I Introduction

    HyQuest Solutions’ WLR 8/15/30 is a highly accurate radar level sensor that measures the distance from the sensor to the surface. It uses advanced 80 GHz radar technology to provide accurate and stable measurements. Using contactless technology for measurement of level of fluids and solids provides many advantages over traditional methods due to simple installation, low power consumption and minimal to no maintenance.

  • Page 7: Part Ii Installation

    Instrument radar beam covers a circular area on the water surface. The radar beam has a 3-dB width angle, subsequently the diameter of the pattern on the water surface depends on the distance of the water surface to the instrument. See Table 3 for pre-calculated pattern dimension. © 2022 HyQuest Solutions...

  • Page 8: Rain And Wind

    Reflections Rain and Wind WLR 8/15/30 instruments has integrated internal software filters to filter out effects of rain, fog or wind for radar distance sensor. These filters however have some limitations. Majority of measurement inaccuracies caused by environmental factors can be solved by proper sensor installation.

    Configuration (formerly Radar Configurator Utility) Configuration (formerly Radar Configurator Utility) HyQuest Solutions provides a user-friendly PC application to configure WLR Water Level Radars. Additionally, the Configurator Utility displays current level readings. When started, the Configurator Utility displays its main window. Initially, no level data is displayed, as the connection to the level meter device is not established.

  • Page 26: Modbus Rtu Protocol (Rs-485)

    Modbus is a request-response protocol where a master (such as datalogger) sends out requests, and slave devices (such as WLR 8/15/30 sensors) responds. The request and response format, with example is given in tables 3-6. In each request, the master can either ask the slave to retrieve value of one or more registers, or the master can set the value of one or more registers.
