The transmitters directly calculate the mass flow or standard volume flow for gases, vapors and liquids with dynamic flow compensation from three process variables of differential pressure, absolute pressure and temperature. They also make it possible for a single device to replace a standard DP transmitter, gauge transmitter, RTD, associated wiring and flow calculator. The instruments can also measure the level of liquid-filled tanks and boiler drum level with temperature and/or pressure dependent density changes of the process medium. With the inclusion of a tank shape specification, they can also measure liquid volume. The units feature TTG (Through The Glass) technology, which allows configuration of the instrument through the glass of the housing cover via four buttons on the display of the transmitter. They also contain a standard HART diagnostic called PILD (Plugged Impulse Line Diagnostics) detection, and provide pulse or frequency outputs for activating external totalizers or for signaling limit-value violation.
