MSR Magmeter
Universal Mount
This diagram shows the individual parts of the Magnum Universal Mounting Unit. It is particularly important to note that, while installing the flowmeter, the lock nuts be loosened (moved some distance away) from the End Nipple and Position Nut. Otherwise both could lock up and make moving or turning of the sensor difficult or damage the thread of the Universal.

The Locking Nuts should only be used once the sensor is in its proper operating position for the given application.
