M322 signal conditioning unit
The M322 signal conditioning unit accepts temperature and flow signals
from the M111 transducer as well as a 4 - 20 mA analogue pressure
signal from an EL2600 pressure transmitter. These signals are
converted into digital form for onward transmission to the M210G flow
computer which can be located up to 300 m away.

Maximum operating temperature: 65°C
Supply voltage - 24 Vdc (from M210G computer)
Channel Input Output
Port 1 Analogue input from Frequency signal
M111 transducer (150 - 1500 Hz) which
proportional to plate is proportional to flow
deflection angle through the M111
(using RVDT) i.e.: flow transducer.
Port 2 Analogue input from Frequency signal
(temperature) Pt100 temperature (150 - 1500 Hz) which
sensor incorporated is proportional to
into M111 transducer measured temperature
Port 3 4 - 20 mA from EL2600 Frequency signal
(pressure) series pressure (150 - 1500 Hz) which
transmitter Max. loop is proportional to
impedance = 150 ohms
Open circuit
voltage = 15 volts
measured pressure
EL2600 pressure transmitter
NB. This is only required for superheated steam applications

'U' Syphon assembly
Process connection
Mount the EL2600 via a ¼" BSPP connection into the 'U' syphon
assembly and mount the 'U' syphon assembly via a ¼" BSPP connection
directly into the pipework.
Full installation details are supplied with the EL2600.
