Characteristics of the measuring instrument
In Table 1 the general characteristics of the electronic calculating and indicating device are presented. The construction of the electronic calculating and indicating device is recorded in the Documentation folder TC8392-3.
The electronic calculating and indicating device TCS 3000 is intended for use on fixed and mobile installations to measure flammable products such as gasoline, diesel, heating oil and LPG. TCS 3000 can calculate the product volume at reference conditions using the measured volume at measured conditions, measured product temperature, the manually input density at reference conditions and the conversion method. Both the manually input density and the conversion method are protected by a seal.
TCS 3000EX is the variation in explosion proof enclosure. It shares the same main board as the TCS 3000, however it has distinct features from TCS 3000 in the interface board, keyboard barrier board and power supply stabilization board.
