Emerson MSP400RH, IP2046IM manual Do not USE Housing to Tighten Ptfe

3.2 Mounting the transmitter above the liquid surface.

A 2” thread is provided to mount the transmitter.

The user should check the thread form, which will be either 2” BSPT (MSP400RH-B28) or 2” NPT (MSP400RH-N28). The thread form is clearly marked on the hexagon of the transducer body.

Note : The MSP400 is designed to be mounted in a non-metallic fitting or flange. The use of metallic fittings or flanges is not recommended.

To help installation, a bracket kit is available from Mobrey. This comprises a Stainless Steel angle bracket and PVC threaded disc which may be used to mount the MSP400 on a gantry or other support over the liquid level. Order part number MSP-BRK2 (BSP) or MSP-BRK3 (NPT). The bracket may be bolted to a suitable cross member above the liquid surface.

Ensure that the transmitter is perpendicular to the liquid surface to maximise the return echo size.

Check that the maximum liquid level will not encroach into the 0.45m blanking zone of the transmitter.

Note : To aid alignment, the echo size / signal strength can be displayed on the MCU900 control unit or on the MSP400RH transmitter display. Refer to section 4 for details.

Use PTFE tape on the screw thread, tighten to hand tight + ¼ turn, using the Hexagon.

When installing on a vessel which has a nozzle or stand-off, and the transducer face does not protrude into the vessel, note the dimensions in the diagram below and always ensure that the nozzle/vessel weld is smooth and free from internal weld beads or other projections.
