HT metering Kiosk is one which has to install between DP structure and HT panel if the distance between them was more than 15 mtrs to reduce voltage drop........
It is a device that measures the differential pressure between two inputs. Example: You have a pressure container where you connect the H-side (high) of the DP-cell. The L-side (low) you leave in the atmosphere (open air). The DP-cell will tell you the pressure in the pressure container relative to atmosphere pressure. Depending on what class the DP-cell is, it will give you feedback with a current signal. Normal in Europe is 4-20 mA, where 4 is lowest and 20 is highest.
