Dear Roy,

At this pressure , non-condensible load estimated is only 2 Kg/Hr. We can provide only N2 to the system , we can not provide even the liquid seal.

Height is required 10 mt, if use water. but it will evaporate immediately at this pressure/Temp.

we can not use mercury for liquid seal.

Do you know any rotameter manufacturer with DP REGULATOR with lowest range of flow capacity.

We are allowed to purge N2 only 0.1 kg/Hr [ 3.5Kg/cm2g]. I have to also Kill this pressure from 3.5 kg/cm2 to lowest possible with 1.2 mm
restriction orifice plates [ adds to joint ].

Any calculations available for leakage estimate?
Any manufacturer give regulator with such low capacity flow?

We could not get through your email , if you can give me the email again ?
