SENSOR FOR MEASUREMENT OF GAS OR LIQUID FLOW RATE |
摘要 |
FIELD: measurement of gas or liquid flow rate in main pipe lines. SUBSTANCE: proposed sensor is provided with additional framework and two temperature-sensitive resistors which are located on hollow framework mounted in housing. Framework with temperature-sensitive resistor and heating element forms lower sensitive element in lower portion of sensor housing. Second framework with temperature-sensitive resistor forms upper sensitive element located in upper portion of sensor housing. Space between sensitive elements is filled with heat-insulating material, thus ensuring smooth heating of lower temperature-sensitive resistor within range of temperatures excluding quick aging of material and excluding effect of other parameters of medium on its readings and automatically compensating for change in temperature. EFFECT: enhanced accuracy of measurement; enhanced mechanical strength. 3 cl, 3 dwg |
