6.0Accessories

6.1Submersion shield

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.

6.2Head Verification Device

The MSP-HVD is a combined mounting bracket and verification device for use with the MSP900SH transmitter, normally used in Open Channel Flow applications.

The HVD is mounted on an arm over the channel and supports the MSP900SH on an integral bracket. A target plate at a fixed distance from the transmitter face may be swung under the transmitter. The level and flow readings calculated by the transmitter in this situation may then be compared to a local calibration plate to ensure that the system is functioning correctly.

Refer to data sheet IP267 for further details.
