The ERW 700 is a flow computer for energy and flow rate calculation of gaseous, vaporous and liquid media. As a MI-004 approved calculation unit it can be used as part of a heat metering system in custody transfer applications. In addition, it is approved according to PTB for use in combination with a cooling meter. The flow computer calculates the (standard) volume, mass and energy of liquids, gases and steam from the input variables flow rate, (differential) pressure, temperature and density.
