FLOATS
Model MR transmitters offer numerous floats for different applications such as stainless steel, 3-A sanitary, hastelloy, Teflon, and Nitrophyl
for both product level and interface level. To be able to accurately detect the interface level there needs to be a difference of at least 0.05 in
specific gravities between the product and interface liquids. For detailed information about floats, refer to the ‘Accessories Catalog’, MTS part
number 551103.
For assistance with selecting a specific float for your application, please contact Technical Support with the following information:
• Specific gravity of liquid(s) being measured
• Process temperature • Process Opening Size
• Vessel pressure
For ATEX, IECEx, and CCoE approvals, Model MR transmitters should be used with a float having an offset weight and made of stainless steel
or Hastelloy C. This allows the float to stay in contact with the pipe to prevent the buildup of an electrostatic charge. For detailed information
about floats, refer to the ‘Accessories Catalog’, MTS part number 551103.
Non-metalic floats with a projected surface area of less than 5,000 mm² should only be used in Zone 0, Gas group IIA such as float part
numbers 201643-2, 201649-2, 201650-2, 201109, 251115 and 251116. All other non-metallic floats offered by MTS such as, 251939,
251119, 251120 and 252999, should not be used in a hazardous area application.

INTERNAL ELECTRONICS
All transmitters come with two electronic components of a sensing element and a board set. All sensing elements up to 300 inches (7620
mm) are rigid and greater lengths have flexible sensing elements. Flexible sensing elements are only available under 300 inches (7620 mm)
as special orders. The board set consists of a electronic puck and interconnect board. The board set can be configured for single or dual loop
output offering the ability to output the product level, interface level, and temperature. All three variables can be communicated via HART.
The electronic puck can be ordered with or without a display. The optional display is capable of displaying the product level, interface level, and
temperature. Designed into the optional display are three push buttons for local setup of 4 and 20 mA set points.
A temperature sensing function is optional with the Model MR transmitter. The temperature sensing device is a Resistive Temperature Device
(RTD) mounted inside the transmitter’s outer pipe assembly. The RTD is a 1000 ohm platinum film device.
ACCESSORIES
MTS also offers a series of displays, housings, converters, and other accessories, please refer to the ‘Accessories Catalog’, MTS part number
551103.

MTS Sensors
Level Plus®Liquid-Level Transmitters - M-Series Model MR Analog Transmitter
Operation and Installation Manual, Part No.: 550720 Revision K (EN) 02/2016
Theory of operation
Magnetostrictive M-Series transmitters precisely sense the posi-
tion of an external float by applying an interrogation pulse to a
waveguide medium. This current pulse causes a magnetic field
to instantly surround the waveguide. The magnet installed within
the float also creates a magnetic field. Where the magnetic fields
from the waveguide and float intersect, a rotational force is created
(waveguide twist). This, in turn, creates a torsional-sonic pulse that
travels along the waveguide as shown in Figure 4.
The head of the transmitter houses the sensing circuit, which de-
tects the torsional-sonic pulse and converts it to an electrical pulse.
The distance from a reference point to the float is determined by
measuring the time interval between the initiating current pulse and
the return pulse and precisely knowing the speed of these pulses.
The time interval is converted into a level measurement.
Figure 4. Theory of operation
Accuracy
For magnetostrictive transmitters inherent accuracy is measured in terms of non-linearity. Non-linearity is a measurement of any imperfec-
tions in the waveguide that are reflected in the linearity of the transmitter’s output. MTS tolerances reflect a maximum non-linearity of 0.02%
of full scale. MTS is able to achieve such strict tolerances by manufacturing all of its own waveguide from a proprietary alloy and testing 100%
of all transmitters before shipping.
Warranty
6
All M-Series transmitters come with a two year limited warranty from
the factory shipment date. A Return Materials Authorization (RMA)
number is required and must accompany any transmitter returns.
Any unit that was used in a process must be properly cleaned in
accordance with OSHA standards, before it is returned to the factory.
A Material Safety Data Sheet (MSDS) must also accompany the
transmitter that was used in any process.
Important:
Contact Technical Support or Customer Service for assistance if you
suspect that the transmitter is not working correctly. Technical support
can assist you with troubleshooting, part replacement, and Returned
Material Authorization (RMA) information if required.

Installation and mounting
If the installation is going to occur in a hazardous area, completely read the Agency Information section before starting any work. The Agency
Information outlines additional regulations that need to be followed in order for the installation to comply with hazardous area regulations.
This section contains information about storing your transmitter (prior to installation) and detailed procedures for installing and mounting your
transmitter.
Storage
If storage is required prior to installation, store indoors in a dry environment at ambient temperature range not exceeding -40 °C (-40 °F) to
71 °C (160 °F).
Stilling wells and guide poles
Level Plus transmitters can be mounted in slotted or unslotted stilling wells but a slotted stilling well is always preferred. Using a unslotted
stilling well will negatively affect performance of any level device as the level in the stilling well can differ from the level in the tank. The Level
Plus transmitter can also be installed to one side of the stilling well to also allow for sampling and manual gauging from the same opening as
the automatic tank gauging. Contact Technical Support for details.
Level Plus transmitters do not require a stilling well for installation. Our transmitters are installed in numerous tanks without stilling wells with
no loss in performance due to our patented flexible waveguide and hose. A stilling well is highly recommended for agitated, turbulent, and/or
fast filling tanks.
Installation
The installation procedures below are illustrated using the adjustable NPT fitting for a threaded flange mount. The procedures will have to be
slightly adjusted if using a welded flange or sanitary Tri-Clamp mount.
RIGID PROBE
Tools Required:
• Channel lock pliers
• Common screwdriver
• 5/32 in. Hex key (allen wrench)
Caution:
It is recommended that assembly and mounting of this transmitter should not be performed alone. To ensure proper and safe assembly of the Level
Plus transmitter, a minimum of two (2) individuals are recommended. Gloves are also recommended. In addition , PPE is required for work areas such
as safety shoes, safety glasses, hard hat, and fire resistant clothing.
Perform the following steps to Install the RefineME transmitter:
1. Remove the stop collar and E-ring. With assistance, feed the rigid pipe through the hole of the removed tank flange until the flange is
positioned near the top of the transmitter. Insert the threaded portion of the adjustable fitting into the customer supplied flange and
tighten (apply pipe thread sealant if required). Be careful not to drop the flange as it can damage the transmitter.
2. Slide the product float onto the rigid pipe. Slide the interface float (optional) onto the rigid pipe. Install stop collar 2 inches from the
bottom (see ‘Note’ below). Do not drop the float(s) or allow them to free fall along the rigid pipe as damage may result.
Note:
The stop collar can be removed or adjusted based on the float selected for the application. Please consult the factory for more information.
3. Slide float(s) back down to the stop collar to prevent them from free falling during installation into the tank. Insert the rigid pipe
(with floats) through the tank opening and lower the transmitter/float assembly into the tank until it rests on the bottom. DO NOT
DROP OR DAMAGE THE PIPE.
4. Secure the flange onto the tank mount.
5. Pull the transmitter upward so the end plug is just resting on the floor of the tank. Tighten the adjustable fitting to hold the transmitter
in place.
6. Terminate the field wire cables noting proper wire orientation.

FLEXIBLE PROBE
Caution:
When assembling and installing the Model MR transmitter, be careful not to allow the flexible hose to kink or be coiled in less than 16 in. (406.5 mm)
diameter. It is recommended that assembly and mounting of this transmitter should not be done alone. To ensure proper and safe assembly of the
Model MR transmitter, a minimum of two (2) individuals are recommended. Gloves are also recommended. PPE is required for work areas such as safe-
ty shoes, safety glasses, hard hat, and fire resistant clothing.
Tools Required:
• 9/16 in. Socket and ratchet
• Channel lock pliers
• 3/16 in. Hex key (allen wrench)
1. Remove the stop collar. With assistance, feed the flexible hose through the hole of the removed tank flange until the flange is
positioned at the rigid section of pipe near the top of the transmitter. Insert the threaded portion of the adjustable fitting into the
customer supplied flange and tighten (apply pipe thread sealant if required). Be careful not to drop flange on the flexible hose as
damage may result.
2. Slide the product float onto the flexible pipe. Slide the interface float (optional) onto the flexible pipe. Install stop collar 3 inches from
the bottom of rigid section (see ‘Note’ below). Do not drop float(s) or allow them to free fall along the flexible pipe as damage may
result.
Note:
The stop collar can be removed or adjusted based on the float selected for the application. Please consult the factory for more information.
3. Mount the hook, weight, or the magnet to the welded end-plug section of the pipe (this is the bottom rigid section of the pipe) using the
supplied nut, spacer and washer, tighten securely as shown in Figure 5. For the magnet, remove washer before
installing in tank.

Mounting
The method of mounting the transmitter is dependent on the vessel or tank in which it is being used, and what type of transmitter is being
mounted. There are three typical methods for mounting; threaded flange mounting, welded flange mounting, and sanitary Tri-Clamp mounting.
THREADED FLANGE MOUNTING
In most applications, the Model MR transmitter can be mounted
directly to the tank or flange via a NPT threaded fitting, assuming
there is a proper threaded connection available. If the float will not fit
through the flange opening when the flange is removed, there must
be some alternative means to mount the float on the transmitter from
inside the vessel; this may require an access port nearby the entry
point of the transmitter as shown in Figure 6.

WELDED FLANGE MOUNTING
The Model MR transmitter can also be mounted to a tank flange as
shown in Figure 7. First, install float(s) onto the transmitter. Second,
install the float retaining hardware on the tip of the transmitter. To
complete the installation, mount the transmitter, flange and float(s)
as a unit in to the tank.

SANITARY TRI-CLAMP MOUNTING
In sanitary applications, the Model MR transmitter is mounted to the tank using a standard sanitary connection and clamp as shown in
Figure 8. In most cases it is not necessary to remove the float as the sanitary end-plug fitting is sized to allow installation with the float in place.
Please note that some sanitary end-plug styles have float(s) permanently mounted as shown in Figure 9. To install the clamp, the transmitter
and float(s) into the mating process connection and attach the sanitary Tri-Clamp.
