  • Page 199 Tankside Monitor NRF81 Operating menu "HTG" submenu Overview Hydrostatic Tank Gauging (HTG) is a method to calculate the level and the density of the product inside a tank using pressure measurements only. The pressure is measured at different heights of the tank using one, two or three pressure sensors. With these data either the density or the level of the product (or both) can be calculated.

  • Page 201 Tankside Monitor NRF81 Operating menu HTG evaluation: dependence on measured level To calculate the level or density by HTG with the required accuracy, P1 and P2 have to be covered by a certain product level. To avoid a measurement with an insufficient accuracy, the calculation will stop before the level reaches the position of the pressure sensor.

  • Page 204 Operating menu Tankside Monitor NRF81 HTG evaluation: dependence on measured pressure If the level of the product approaches the the P1 or P2 pressure sensor, the measured pressure becomes very small and the measurement might be too inaccurate for the Tank Gauging application.
  • Page 205 Tankside Monitor NRF81 Operating menu Hysteresis The level of the product in a tank is not constant but slightly varies, due for example to filling disturbances. If the level oscillates around the changeover level (Minimum level), the algorithm will constantly switch between calculating the value and holding the previous result.
