Description

MPXI-F Series Explosion Proof, Flexible Stainless Steel and PVDF Stem Magnetostrictive Probe Level Sensors’ flexible stem allows for installation in tanks up to 50 feet tall, without needing a crane or an extra-long truck and trailer for delivery. It provides highly accurate and repeatable level readings in a wide variety of liquid level measurement applications. APG’s proprietary-PVDF-formulation stem provides increased flexibility and impact resistance during cold-weather installation, along with compatibility in a wider range of corrosive media–including H2S–in larger tanks. The housing is certified for installtion in Class I, Division 1 and Class I, Zone 1 hazardous areas, while the stem is certified for installation in Class I, Division 1, and Class I, Zone 0 hazardous areas in the US and Canada by CSA and ATEX and IECEx for Europe and the rest of the world.

Installation Guidelines

The MPXI-F should be installed in an area–indoors or outdoors–which meets the following conditions:

• Ambient temperature between -40°C and 85°C (-40°F to +185°F)
• Relative humidity up to 100%
• Altitude up to 2000 meters (6560 feet)
• IEC-664-1 Conductive Pollution Degree 1 or 2
• IEC 61010-1 Measurement Category II
• No chemical corrosive to stainless steel (such as NH3, SO2, Cl2, etc.). (Not applicable to plastic-type stem options)
• Ample space for maintenance and inspection

Additional care must be taken to ensure:

• The probe is located away from strong magnetic fields, such as those produced by motors, transformers, solenoid valves, etc.
• The medium is free from metallic substances and other foreign matter.
• The probe is not exposed to excessive vibration.
• The float(s) fit through the mounting hole. If the float(s) does/do not fit, it/they must be mounted on the stem from inside the vessel being monitored.
• The float(s) is/are oriented properly on the stem (See Figure 5.1 below). MPXI-F floats are installed by customer.
• When lifting and installing the sensor, be sure to minimize the bending angle between the rigid stem at the top and bottom of the sensor and the flexible stem in-between. Sharp bends at those points could damage the sensor.

ATEX Stated Conditions of Use:

• Under certain extreme circumstances, the non-metalic parts incorporated in the enclosure of this equipment may generate an ignition-capable level of electrostatic charge. Therefore the equipment shall not be installed in a location where the external conditions are conducive to the build-up of electrostatic charge on such surfaces. In addition, the equipment shall only be cleaned with a damp cloth.
• The enclosure is manufactured from Aluminum. In rare cases, ignition sources due to impact and friction sparks could occur. This shall be considered during installation.
• Unused conduit entries shall be closed with blanking elements maintaining explosion-proof properties and ingress protection rating of the enclosure and are removable only with the use of a tool.
• Wiring used for external connections shall be rated at least 20°C higher than the maximum ambient temperature.
• Conduit seal shall be installed within 18” of enclosure.
• MPXI shall be supplied by Class 2 or limited energy source according to C22.2 NO 61010-1 and UL 61010-1.

PVDF Installation Temperature Requirements

Prior to installing a PVDF-stem MPXI-F, the interior, mid-column temperature of the tank must be measured to determine the amount clearance needed at the bottom of the probe for thermal expansion. See Figure 7.1.

1. Determine interior, mid-column temperature in °F.
2. Determine interior tank height from top of probe mounting to tank interior bottom, in inches.
3. Use formula in Figure 7.1to determine necessary clearance from bottom of probe to interior tank bottom.
4. If necessary, adjust placement of slide mount on probe to accomodate required clearance.

Contact factory with any PVDF-stem thermal expansion requirement questions.

• PROBE CLEARANCE = .000108
• (185 – INSTALL TEMPERATURE)
• INTERNAL TANK HEIGHT

† TEMPERATURE IN DEG. F LENGTH IN INCHES

Physical Installation Instructions

Ensure that all components have been received, including:

• MPXI-F sensor (head and stem, slide mount if purchased)
• Float or floats, if purchased from APG
• Stem Weight(s); Weight-Locking Pin and Set Screw for SS; Top Weight Retention Ring (with two screws), Dowel Pin for PVDF
• Assembly drawing

Assemble sensor mounting, float(s), weight and pins at installation location, if possible.

• If not already attached, slide mounting option onto stem. Loosen compression cap so it will slide easily on stem. For probes with PVDF stems, be sure to account for thermal expansion clearance (see section 7) when placing slide mount on stem.
• For SS sensors with float stops, refer to the assembly drawing included with the sensor for float stop installation locations. PVDF float stops are installed at the factory.
• Note: If the floats do not fit through the tank/vessel mounting hole, mount them on the stem from inside the vessel being monitored. Then secure the sensor to the vessel.
• Slide floats onto stem. If using two floats, slide the lighter float on first. Tops of floats will be indicated by sticker, taper, or etching on float. (See Figure 5.1) After ensuring top of float is toward MPXI-F sensor head, remove sticker(s).
• For PVDF stem:
  • Slide weight retention ring onto stem, then insert weight(s) on end of stem
  • Secure dowel pin in end of stem (use hammer/mallet if necessary)
  • Slide weight(s) down onto dowel pin
  • Lock weight(s) in place by sliding weight retention ring down to top weight, tighten ring
• For SS stem:
  • Insert weight(s) on end of stem
  • Insert weight-locking pin into end plug hole
  • Lock into place with set screw, using 1/8” allen wrench
• Install MPXI-F sensor on tank
  • When lifting and installing the sensor, be sure to minimize the bending angle between the rigid stem at the top and bottom of the sensor and the flexible stem in-between. Sharp bends at those points could damage the sensor. The 10” bend radius of the PVDF probe’s shipping box can be used as a guide for the smallest allowable bend for the PVDF stem (see PVDF Shipping Box Contents, section 4).
  • If your sensor’s stem and float(s) fit through the mounting hole, insert the weight and the floats into the mount opening.
  • Carefully unroll and feed the MPXI-F sensor stem into the tank, being careful to not let the float(s) drop uncontrolled on the stem. Slide the mount up to the top of the stem.
• For PVDF stem:
  • When the weight is on the bottom of the tank, secure the mounting option to the vessel
  • Take any slack out of the flexible stem, raising bottom of stem to previously calculated clearance height (see section 7).
  • Tighten the compression fitting to hold stem in place.
• For SS stem:
  • When the weight is on the bottom of the tank, secure the mounting option to the vessel.
  • Take any slack out of the flexible stem.
  • Tighten the compression fitting to hold stem in place.

NOTE: Damage due to floats dropped on stem may not be be covered by warranty.

Electrical Installation Instructions

NOTE: For MPXI-F7 series sensors, – VDC from power source must be connected to Out1 on sensor for correct sensor programming.

General Care

Your level sensor is very low maintenance and will need little care as long as it was installed correctly. However, in general, you should periodically inspect your MPXI-F to ensure the stem is free of any heavy buildup that might impede the movement of the float(s). If sediment or other foreign matter becomes trapped between the stem and float(s), detection errors can occur. If you need to remove the float(s) from the stem of your MPXI-F, be sure to note the orientation of the float(s) prior to removal. This will help ensure proper re-installation of the float(s). Also, ensure that the housing cover is snuggly secured. If the cover becomes damaged or is misplaced, order a replacement immediately.

NOTE: Damage due to floats dropped on stem may not be be covered by warranty.
