The development stage readiness: Introduced in production

Description of the development:
()
The system of "Strings" provides: "High-precision measurement of distance, density and temperature of liquids, including food and hazardous liquids (gasoline, JP, oils, alcohols, kerosene, LPG, etc.); "Calculation of volume and mass calibration table of tanks; "A fully automated accounting movement of petroleum products at gas stations when used in conjunction with the systems of leave; "Automatic control of single-and double-walled containment (liquid-filled) tank with the inclusion of sound and light alarms; "To prevent overflow of fuel during the filling of tanks, by a control signal to turn off the pump switch (off), sound and light alarms; "Displays the results of measurement and calculation of parameters on a standalone display, or (ii) output to the user's computer via standard interface RS-232C, RS-485, USB; "Metrological calibration without removing the equipment; "Significant reduction in downtime for the transfer station change; "Transfer of measured data on the cell phone user and a remote computer over the GSM 900/1800; "Transfer of information on the state of security and fire alarm monitoring system for GSM tanks.
