Fig. 15b Schematic drawing of connections to the SE 4025 ultrasonic flow meter
Note the connections of probes 1 and 2 (1,2,3 and 4 at SE 4025), necessary for the correct meter operation. For
probe marking see Fig. 13.
Connected to terminal strip X1 are, apart from the ultrasonic probes, the feeding power lines, signal outputs (the
impulse, frequency, current and relay outputs) and the RS 485 communication interface.
The X4 CANON 9 connector serves the purpose of connecting the RS 485 interface used in the meter calibration,
servicing and in-company operational setting.
The X6 terminal strip is used to connect the Pt 100 temperature sensor in the optional mass-flow-rate meter
configuration.
By shorting the jumpers W4 and W6 the impulse output will be activated; the same action on jumpers W5 and W6
activates the frequency output. If the impulse or frequency outputs are used in the passive mode of operation (jumpers
W4 through to W6 disconnected), the optron current shall not exceed 20mA. The S1 push-button can be used to reset
the total fluid volume reading to zero; the same command can be sent via the RS 485 line. To indicate the fluid flow
direction, connect to terminals 1 and 2 on terminal strip X1 a relay coil in series with external alternating voltage source
24 V/100 mA.
Push the arresting pin on the right-hand side of the electronic unit box upwards and lift off the front panel to the left
to gain access to switch S3 through the respective circular hole in the top printed circuit board of the unit.
