External Structure

SELECTION OF DAMPER
APPLICATION
• Cavitation, liquid hammer and pressure peaks may occur in air or liquid systems with varying flow rates. For example, the rapid closing of the valve or the start and stop of the pump.
• Even at relatively low operating pressures, these problems may occur at the inlet and outlet.

MEDIUM CONDITIONS
In liquids containing particles, nozzle clogging may occur. Mounting the transmitter vertically can minimize the risk of clogging because the flow of fluid is limited to the initial start-up, while the volume at the rear of the nozzle is fixed anothe aperture of the nozzle is relatively large (1.2 mm).
The viscosity of the medium has little effect on the response time. Even if the viscosity reaches 100 CST, the response time will not exceed 4 ms.
