The panelmeter 2028 is specially designed to satisfy the needs of massflow indication in difficult applications where other flowmeters are unsuitable or difficult to use, such as measurement of solid matters or molten metal. Based on the current signal of a strain gauge transmitter the panelmeter 2028 calculates the change of the weight per second and in that way shows the actual flow rate.

Typical applications are reservoirs containing solid materials or liquids whose emptying or filling process is monitored and controlled on the basis of the flow rate. This measuring method enables indication of the flow rate in two directions, i.e. during the filling or the emptying.

Decompression chamber units are typical  applications where adjusting of changing speed of pressure is important.
