and steel needle, and it is also not allowed to press the diaphragm with hands,
so as not to damage the diaphragm or cause the diaphragm to deform.
3.2.2.1 Installation in still water:
a) The installation method in the pool is shown in Figure 2. In order to
prevent the impact of the pump from shaking and damaging the
transmitter, the transmitter should be placed away from the liquid
inlet and outlet. Otherwise, the steel pipe protection method shown
in Figure 3 should be used.
b) The installation in the deep well is shown in Figure 3. Generally, the
method of inserting steel pipes is used. It is required that the steel
pipe cannot be bent, and the inner diameter must be larger than the
outer diameter of the transmitter. Several small holes are punched at
different heights of the steel pipe to facilitate the smooth entry of
water into the pipe. If necessary, wind a steel wire around the
transmitter and lift it up and down with the steel wire to avoid
breaking the cable.
