Installation, Operation & Maintenance Manual IP2040/IM, Rev. AA May 2007 1.0 MSP900SH Introduction The MSP900 ultrasonic level transmitter is designed to be mounted above a liquid and will measure the distance to the liquid surface. When programmed with details of the vessel, sump or open channel, the MSP900 will compute level, contents or flow and give a 4-20mA signal proportional to the chosen variable. Full programming details are given in the Operating Manual IP2040/OM.

Installation, Operation & Maintenance Manual MSP900SH • IP2040/IM, Rev. AA May 2007 In many installations, the use of a calibration device is mandatory. Mobrey Measurement offer the MSP-HVD for this purpose, details on request. In order to minimise measurement uncertainties when a calibration device is installed, it is recommended that the calibrated range should be kept to a realistic minimum. i.e. max flow plus 10mm.

Installation, Operation & Maintenance Manual IP2040/IM, Rev. AA May 2007 MSP900SH 3.6.1 Wiring When connecting the MSP900SH transmitter to an MSP90 Series control unit, different terminals are used in the control unit. If connected, disconnect the existing MSP90 type transducer. These terminals are not used with the new MSP900SH type transmitters.

AA May 2007 The MSP-SUB2 is a tubular shield which slips over the black transmitter front housing. This is usually fitted in wet well installations where the liquid level could rise faster than the pumps can pump out. As the liquid covers the transmitter, an air-lock is created in the shield and the transmitter face remains free from contamination. 6.
