product structure
Precautions
The use of a transmitter side exhaust / drain valve, taps should be
installed to the side
flow pipeline. Working medium for the level, exhaust gas / liquid
discharging valve arranged
on the flange of the upper to exhaust gas; working medium for the
gas, vent / drain valve
installed in the lower flange to discharge liquid; flange rotation
of 180 DEG, side exhaust /
drain valve from the upper to the lower.
Note: The measurement of steam or other high temperature media,
medium
temperature can not contact with the transmitter over its use for
temperature limit.
When measuring steam, the pressure inside the tube must be filled
with water, to
prevent direct contact with steam and transmitter. Because the
volume change quantity
transmitter is very small, so it does not require the condenser.
Pipeline pressure port connecting the transmitter and the measured
media is a
transmission channel pressure, the pressure transfer process,
factors may introduce error
include
1) Loss of pressure
2) The friction loss of pressure pipe
3) The accumulated gas of pipeline in the liquid medium
4) The accumulated liquid of pipeline in the gas medium
Installation with mounting bracket
2 inch pipe vertical bracket
