    4. INSTALLATION To create chance for replacing the instrument during operation, the use of closing armature is recommended. A simple ballcock valve will be suitable for lower pressures, but for higher ones (above 6 bar) a three-way blow-off needle-valve is suggested. In case of level measurement, it is advisable to screw the transmitter to the stump on the side of the tank.
