Fuel level sensors Strela
Fuel level sensors Strela are intended for use in vehicles and petrol, oil, lubricants(POL) depots in systems that measure and control amount of POL: petrol, diesel fuel, winter diesel fuel, oil. Fuel level sensor Strela measures fuel level and forms a signal, proportional to the level of fuel in tank Can be used with GPS-monitoring devices: Ruptela, Teltonika, Galileo etc. Standart interfaces: analog (0-10 or 0-5V), frequency(500-1500 Hz.), RS232, RS485 (Modbus, Omnicomm).
Advantages
– possibility of calibration of sensors of any type including analog and frequency;
– electric insulation of sensor head from the tank;
– adjustable range from 1023 to 4096 points per sensor length;
– possibility of FLS’s calibration (level-volume), which allows to get straight a volume
sensor;
– possibility to use thermal compensation and codes of self diagnostics;
– protection from polarity reversal, short circuit of the output to the ground (in some devices
short circuit of the output to plus );
– availability of devices used for sensor linking to the staff vehicle dashboard;
– availability of FLS’s sumators used for data processing of multitank systems;
– length up to 4000mm, possibility trimming to any length, availability of sectional sensors.

*Is correct for sensors, which are calibrated (it is recommend) after cutting, without calibration is acceptable
length of cutting for Strela A and Strela F sensors no more then to 50% of initial length, in such case the output value
range min and max shifts.
