Instruction for installation
- Before purchasing this product, please check for possible problems with the installation
- Contact us by phone or email to discuss any questions or concerns you might have
- Use the device only in the right ambient conditions (read the specifications).
- The device must not be installed in a hazardous environment (94/9/EG)
- If the device is installed too close to the tanks side wall, it is possible that reflections
cause problems to the accuracy of the measurement, due to the characteristics of
the ultrasonic pulses being reflected off the wall.
- The device should be installed in the center of the tank. As a guideline there should be a minimum
distance of 5 inch from the wall to the installation opening.
- The LC-indicator should be mounted, where the ultrasonic pulses can beam without obstruction to the
bottom, or lowest level of the tank.
- Built- in parts can disturb the ultrasonic pulses and may result in a false measurement (e.g. pipe,
manhole, cross beam).
- It is recommended to verify the location of the installation when the tank is empty, as it is possible to
see potential obstructions, which may cause the ultrasonic pulses to be reflected before reaching the
bottom of the tank.
- The calculated medium value (will be calculated by the measured distance) always relates to the level
of the sensor inside of the conus (this sensor is situated between the smaller and the bigger thread).
- The maximum distance between medium level and sensor can be adjusted with the offset.
- The device has a min. and max. measurement range (please refer to the specifications); if you work
beyond this specifications you get wrong or no data.
- For a correct measurement you have to ensure that the distance from the sensor to the maximum filling
level is not below the minimum measurement range.
- The device must be installed perpendicular to the fluid surface, because otherwise the reflected
ultrasonic pulses cannot be received.
- The sensor and the controller are not allowed to contact the medium which is to be measured.
- Be sure, that your tank manufacturer allows the installation
and the tank has a minimum entry of 1.5 inch, ideally 2” BSP thread.
- The mathematical calculation in this device is designed only for cylindrical
and cubic tank shapes, special shapes are not supported.
- Only a specialist licensed company is allowed to modify the tank,
in case there is a need to drill or cut holes in the tank! –
you lose the warranty and in case of damage you are personally liable.
- Wrap the thread with Teflon tape to ensure the impermeability of the tank.
- For devices with cable to the sensor, refer to the legal requirements for electronic installations
(e.g.: separate cable routing of low-voltage lines).
- If the tank is refuelled (actual tank contents is higher than the value from the day before) the statistics
(average day demand, remaining days) are reset automatically.
- Please note that the battery life of the device depends on the settings, like permanent display.
- The LC is a simple device, which helps you to measure tank contents.
As any electronic device it is possible to have failures, so the display might show wrong values or not
have any display at all. Always monitor the system to ensure it provides correct data and allows you to
manage your supply to avoid problems, e.g. an empty tank.
- Take the time (which you have saved with our device) and control the tank frequently, so that it is
always in proper condition.
- Please note the legal requirements for your tank and if you have concerns ask a licensed specialty
company.
- Always take a look to the service intervals of your tank and a specialist licensed company should advise
you, that your tank meets the legal requirements (e.g. heating oil tanks should be equipped with a limit
indicator for working with overfill protection systems).
- Important: LC 100 –103 is only for the purpose of tank level indication in non-hazardous liquid storage
tanks. Any other use or application are not at Secu-Tech or Secu-Tech Distributor´s responsibility.
