Description

The Model 3655 and 4655 are Multipoint Settlement Systems comprising of a series of sensitive Semiconductor Pressure Transducers (3655) or Vibrating Wire Pressure Transducers (4655) connected together with a special Nylon tube filled with de-aired water or, where necessary, a de-aired water/antifreeze mixture. The string of sensors is connected to a common reservoir with a large liquid capacity. In use any change in elevation of a sensor will result in a change in the pressure measured by that sensor. Since all the sensors share the same liquid line and are referenced to the same liquid elevation in the reservoir, changes in the sensor elevations, relative to one another can be measured.
