Emerson Process Management MSP-ULOG1 Application/Duty Flow Measurement, Requirement, Input Data

Start the “Duty” Wizard by pressing the yellow (ENTER) key once.

Application/Duty: Flow Measurement

1. With power on and the MSP900SH transmitter giving a 4-20mA signal to the MCULOG unit (see previous pages), you can now programme the MCULOG for an application. This application example is for flow measurements.

Requirement

Live flow measurements in units of cubic metres per second.

Totalised flow in cubic metres per second.

Input Data

Channel Shape: Flume

Maximum depth: 1 metre

Maximum rate: 1 cubic metre per second

The MSP900SH transmitter is supplying live level measurements in units of metres.

Output Data

The MCULOG will be calculating the flow rate.

Logging

See pages 8/9.

2. Navigate the menu system to get to the “Duty Wizard” screen. Key-press hints are alongside the screens.

3.

4. Work through the “Duty” Wizard prompts until completion; this occurs when the menu system re-appears. Keypad hints, for the illustrated Wizard sequence on the next page, are provided alongside the prompts. If applicable, adapt the example to suit your application.

5. Circled numbers in the illustrated Wizard sequence relate to these notes:

cSelect “Flow” from the multiple-choice list.

dEnter the maximum rate of flow.

eEnter the present height of maximum flow in the Flume.

fOption of registering flow as 0 m3/s on the MCULOG while the measured flow rate is below a programmed cut off.

gProgramme the 4-20mA output span with a flow rate range (e.g. 0 m3/s to 1 m3/s)

hOption to set-up a relay to output (100ms) pulses representing the totalised flow.

6.Return to the main menu by holding the ESC key for a few seconds, releasing it when the main menu appears. Next, go on-line by selecting the “Go on-line” menu option and then pressing the ENTER key once. Finally, press the ESC key repeatedly until the primary display appears. The flow measurement will be live on the primary display.
