3.10 Flow Sensor (Option)
The optional Flow Sensor Kit (P/N 068564) provides a sensor for measuring the
liquid flow rate in a stream. Flow rate readings from the sensor are displayed on
the SP ePanel in Chromeleon 7. The sensor can measure flow from 0.2 to
5.0 mL/min. The operating pressure for the flow sensor must be less than
0.28 MPa (40 psi). The resolution of data is 16 bits and the accuracy is 5% of the
measured value. Up to two flow sensors can be installed in the SP.
High and low limits for the flow rate are entered in the Chromeleon 7 Instrument
Configuration Manager. If the flow rate is outside the specified range, the sensor
reports the error to Chromeleon 7 and an error message is displayed in the audit
trail.
To install the flow sensor:
1. Turn off the SP power.
2. Disconnect the power cord.
3. Using the screws and washers provided in the Flow Sensor Kit, attach the
flow sensor to the mounting plate as shown in Figure 3-31 . Make sure the
nylon washers are installed between the board on the flow sensor and the
mounting plate.
