In addition, through the pressure it is possible infer a series of other process variables, like level, volume, flow and density. They also vary some from sensor to sensor perhaps 10%. A multimeter often has multiple testing sockets, according to whether it is being used to test for resistance, voltage, or amperage (current). The measuring resistor RM is chosen to maximize the. 190 million people are enrolled in plans that report HEDIS results. The gauge is the collection of all of the active elements of the Wheatstone bridge.
