Installation Method - Microsensor MDM4901FL Operation Manual

3.2 Installation
3.2.1 Attentions before installation:
a) The operating pressure of measuring medium is no more than
the static pressure of transmitter;
b) The differential pressure of measuring medium in the worksite is
no more than the maximum pressure.
c) For positive and negative pressure balance and convenient
repair, we recommend to use tri-valve （such as J23SA）to connect with
the leading tube, to prevent one-side overpressure destroying the
transmitter. Or the customer can buy the leading tube and tri-valve from
our factory. Tri-valve operation method can see appendix "Tri-valve
Operation Menu".
