Introduction
Thank you for purchasing an MPI series magnetostrictive level sensor from APG. We appreciate your
business and your trust. Please take a few minutes to familiarize yourself with your MPI and this manual.
The MPI series magnetostrictive level sensor provides highly accurate and repeatable level readings in a
wide variety of liquid level measurement applications. It is certied for installation in Class I, Division 1 and
Class I, Zones 0 hazardous areas in the US and Canada by CSA, and ATEX and IECEx for Europe and the rest
of the world. The MPI-R’s large, buoyant, and robust oats allow it to be used in harsh applications where
fouling or buildup might otherwise be of concern. The smaller, lighter weight oats of the MPI-E allow it
to be used in applications where space is limited. The MPI-E Chemical has a chemical resistant coating,
allowing for use in corrosive, acidic, and marine environments.
Reading your label
Every APG instrument comes with a label that includes the instrument’s model number, part number,
and serial number. Please ensure that the part number on your label matches your order. The following
electrical ratings and approvals are also listed on the label. Please refer to the Certicate of Compliance at
the back of this manual for further details.

DANGER: WARNING -- EXPLOSION HAZARD -- SUBSTITUTION OF COMPONENTS MAY IMPAIR INTRINSIC
SAFETY;
AVERTISSEMENT -- RISQUE D’EXPLOSION -- LA SUBSTITION DE COMPOSANT PEUT AMELIORER LA SECURITE
INTRINSIQUE.
DANGER: WARNING -- EXPLOSION HAZARD -- DO NOT DISCONNECT EQUIPMENT UNLESS POWER HAS
BEEN SWITCHED OFF OR THE AREA IS KNOWN TO BE NON-HAZARDOUS;
AVERTISSEMENT -- RISQUE D’EXPLOSION -- AVANT DE DECONNECTER L’EQUIPEMENT, COUPER LE COURANT
OU S’ASSURER QUE L’EMPLACEMENT EST DESIGNE NON DANGEREUX.
DANGER: OPEN CIRCUIT BEFORE REMOVING COVER or KEEP COVER TIGHT WHILE CIRCUITS ARE ALIVE;
AVERTISSEMENT -- COUPER LE COURANT AVANT D’ENLEVER LE COUVERCLE, ou GARDER LE COUVERCLE
FERME TANT QUE LES CIRCUITS SONT SOUS TENSION.
IMPORTANT: MPI level sensor MUST be installed according to drawing 9005491
(Intrinsically Safe Installation Drawing for Hazardous Locations) on page 26 to meet listed
approvals. Faulty installation will invalidate all safety approvals and ratings.
IMPORTANT: Only the combustion gas detection performance of the instrument has
been tested.
