Product Description

Main advantages:

- Tank contents in litres and volume percent

- Ullage display (how many litres can be delivered)

- Calculation of average daily demand in litres/day

- Calculation of the remaining days based on average daily demand

- 3 different tank shapes are supported by appropriate calculations
Easy Installation
No moving components in the tank
Contactless measurement with ultra sonic pulses for optimal reliability
temperature

Applications:

heating oil tanks
waste oil tanks
water tanks
rainwater tanks
as a replacement for mechanical gauge indicators
…….

Installation Instruction

- Before you make a purchase please check for possible problems at the installation,

- Discuss on the phone, write, and e-mail or use the possibility of an individual meeting with our
field staff.

- 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 near to a wall, it is possible that reflections

can cause problems to the measurement, because of the characteristic of
the ultra sonic pulses are reflected off the wall.

- The device should be installed in the middle of the tank, as indication you
should install at least a min. distance of 5 cm from the wall to the aperture.

- The indicator should be in a position where the ultra sonic pulses can beam unhindered to the
bottom of the tank.

- Built- in parts can disturb the ultrasonic pulses and may result a false measurement (e.g. pipe,
manhole, cross beam).

- Check the installation situation when the tank is empty, because if the tank is full you cannot
see the built-in parts which can reflect the ultra sonic pulses.

- The calculated medium value (will be calculated by the measured distance) always relates to
the level of the sensor inside of the cone (this sensor is situated at the height of the bigger
external thread).

- The distance between medium level and sensor can be adjusted with the offset.

- The device has a min. and max. Measurement range (look at the specifications), if you work
beyond this specifications you will get wrong or no data.

- For a correct measurement you have to consider that the distance from the sensor to the
maximum filling level is not lesser as the min. measurement range.

- The device must be installed perpendicular to the fluid surface, because otherwise the reflected
ultra sonic pulses can´t be received.

- The sensor and the controller are not allowed to contact the medium which

you want to measure.

- 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 the LC device is designed only for cylindrical and cubic tank
types, special shapes can´t be considered.

- 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 a good seal with the tank.

- 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 from settings like permanent display and
measurement in the test mode.

- The LC is a simple device, which helps you to measure tank contents.

This is an electronic device and so it is possible to get an error so that the display shows wrong

values. Always monitor the system to ensure it provides correct data and allows you to ensure
manage your stocks to avoid problems, e.g. an empty tank.

- Take the time (which you have saved with the LC device) and control the tank continuous, so
that it is always in good order and condition.

- Please note the legal requirements for your tank and if you have concerns ask a license
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 system

- For using the SMS-function it is necessary that a sufficient telephone network is available. If the
signal from the telephone network is bad (no signal) then the LC200 hasn´t the possibility to
send a SMS.

Checking the contents of delivery

Please, check the contents of delivery immediately after receipt and unpacking.
In case of missing components or transport damages contact your local dealer
or our representative.

Hint: Please keep the original packing material if you have to send the instrument to a service

facility. Keep these operating instructions in case you hand over the instruments to another
person.

Additional application with external mains power supply LC201

1, LC201 can perform measurements with short time intervals.
"Sen GSM" ** the setting has two additional functions:
4 = measured every 2 hours
5 = measurement every 10 seconds
Note: Alarm or error text will be sent only if a limit has been exceeded or undershot.

Important:
LC201 performs a measurement only if the registration was successful in the GSM network.
(Antenna icon with at minimum two strokes).
If SIM card is not inserted, the LC201will not take any measurements.
Alarm SMS is sent only after 7 days and only if the alarm is repeated on two consecutive

days.

Daily SMS:
To set the daily text message, press the button on the default display mode for longer than
10 seconds. It is first setup and then GS Day On display at the display. The daily SMS is now
activated.
To reinstall daily SMS press the button again 10 sec.(GS DAY OFF)

2, Current Remote Tank Contents Measurement
A current remote tank content measurement can be taken at anytime.
Send a text massage M from your mobile or PC. The LC 201 will take a new measurement
immediately and send a return SMS with the current measurement.
For remote measurement: GSM must be registered.
LC 201 sends back to all registered phone numbers!!

Maintenance, Troubleshooting, Service

The device does not need any maintenance.Clean the inside of the sensor cone once a year with a
dry cloth to avoid dirt and debris which could influence the beam of the ultra sonic pulses.
Make a visual check of the batteries once a year. Depending on the charge of batteries you have to
change them.
If the device shows unexpected behaviour try to reset the instrument using the Reset button.
Check your installation (look at the instructions for installation).
If the problem persists contact our service team or send the device to an authorised service facility.
If the device is damaged, remove it immediately from your tank and send it to an authorised service
facility.
If the device is removed close the tank entry after that so that the vapours can´t escape.
