MCU90F & MSP900 Series
Mobrey MCU/MSP ultrasonic level measurement and control systems for level and flow applications have a long and successful history in open channel flow measurement and logging. The MCU90F is the latest addition to this family and is a dedicated open channel flow meter and control unit based upon the highly successful MCULOG.
A Solartron Mobrey open channel flow measurement system comprises an MCU90F control unit and a 4-20mA, HART loop powered MSP900 series ultrasonic level transmitter. A 9700 hydrostatic electronic level transmitter may also be used.
The MCU90F has an integral programming keypad which eliminates the need for a handheld programmer. The MCU90F communicates digitally with the MSP900 series transmitter to give improved resolution and accuracy and is available in wall or panel mounted options.
Features
- ATEX II (1) G
- Calculates flow in an open channels in accordance with BS3680 Pt. 4, ISO14381/1 and ISO4359
- OCF calculation for Parshall flumes
- Clear local back lit display of:
- Instantaneous flow
- Daily totalised flow
- Cumulative flow
- On-board logging of up to 7200 flow values and 365 daily flow rates
- Current output can be proportional to instantaneous flow rate or to a rolling average of flow over a user defined averaging period
- Relays can be allocated as flow rate alarms or may be selected as a pulse output to an external totaliser
Benefits
- Powerful logger allows download at a later date
- Versatile current output options to suit your requirements
- Can be used for flow rate alarms
- Offers low cost alternative to PLC
- Both wall and panel mounted options available
Applications
The flow in an open channel may be derived by measuring the liquid level of a weir or flume of a standard design:

 |
| V notch weir Typical 5/2 power law |
Venturi flume Typical 3/2 power law |
