Model MR - Transmitter with Analog Output

The Level Plus® Model MR level transmitter satisfies the demand for an analog communication interface that offers the liquid-level marketplace unsurpassed flexibility to meet most process application conditions. The Level Plus Model MR transmitter provides 3-in-1 measurement using one process opening for product level, interface level, and temperature measurements. Once the transmitter is installed and calibrated there is no requirement for scheduled maintenance or recalibration. Set it and forget it! 

Level Plus Model MR transmitters are modular in design, offering you a selection of electronic housing styles, transmitter pipe styles and wetted materials. The Level Plus Model MR transmitter features a removable sensing element and can also incorporate an RTD for spot temperature measurement. Subject to local electrical codes, the sensing element and electronics housing can be removed from the transmitter pipe without disturbing the operation of your process saving both time and money.

Up to two 4 to 20 mA loops are available for analog indication of level, interface, and/or temperature. HART® communication allows the Model MR transmitter to indicate and display all three measurement variables simultaneously. Set-up, calibration, and diagnostics are available from any point in the loop using a standard HART hand-held communicator. An optional on-board display and keypad is also provided for local indication and programming.

Model MG - Transmitter with Digital Output

The Level Plus® M-Series Model MG level transmitter satisfies the demand for a digital communication interface that offers the liquid-level marketplace unsurpassed flexibility to meet most process application conditions. The Level Plus Model MG transmitter provides 3-in-1 measurement using one process opening for product level, interface level, and temperature measurements. Once the transmitter is installed and calibrated there is no requirement for scheduled maintenance or recalibration. Set it and forget it! 

Level Plus Model MG transmitters are modular in design, offering you a selection of electronic housing styles, transmitter pipe styles and wetted materials. The Level Plus Model MG transmitter features a removable sensing element and can also incorporate 1, 5, or 12 temperature measurement points depending on the output. Subject to local electrical codes, the sensing element and electronics housing can be removed from the transmitter pipe without disrupting the operation of your process saving you time and money.

Outputs for the Level Plus Model MG transmitter include Modbus, FOUNDATION™ fieldbus, and DDA (a proprietary ASCII protocol).  Modbus and DDA outputs are communicated via a 4-wire multi-drop power and data bus (EIA 485), whereas FOUNDATION™ fieldbus has a specified 3-wire bus. Utilizing the bus network eliminates the requirements for individual cable runs from each tank and these three data formats provide a direct interface to most types of computers and digital communication equipment. Both Modbus and FOUNDATION™ fieldbus outputs also allow a user to measure volume from a 100 point strap table with the option for temperature correction.

Model MC420 - Transmitter with Analog Output

The Level Plus® Model MC420 level transmitter satisfies the demand for an economical analog communication interface offering for hazardous area applications. The Model MC420 provides a single-channel analog 4 to 20 mA output for either a product level or an interface level measurement depending on the application and the selected float. The Model MC420 transmitter is approved by FM, CSA, and ATEX for use in Intrinsically Safe applications. Appropriate barriers are required when installing the Model MC420 transmitter in hazardous areas.

In addition to the single-channel 4 to 20 mA loop, the Model MC420 transmitter provides the HART® field communications protocol for setup and calibration. Calibration can also be accomplished using integrated reed switches and a supplied magnet without the need for expensive electronics. Once the transmitter is installed and calibrated there is no requirement for scheduled maintenance or recalibration. Set it and forget it!

The Model MC420 transmitter is available in set lengths from 457 mm (18 in.) to 5486 mm (216 in.) and can be installed in applications with process temperatures between -40 °C (-40 °F) to 125 °C (257 °F). The electronics are permanently sealed in a NEMA Type 4X rated housing made of 316L stainless steel that provides protection against corrosion and resistance to harsh process conditions.

Model USTD II - Underground Storage Tank Level Sensing for Leak Detection and Inventory Monitoring

The Level Plus® Model USTD II level transmitter is designed for use in Underground Storage Tanks (UST). The most common UST application is containing automotive fuels at gas stations. The Model USTD II transmitter provides 3-in-1 measurement using one process opening for product level, interface level, and temperature measurements. Once the transmitter is installed and calibrated, there is no requirement for scheduled maintenance or recalibration. Set it and forget it!

The Model USTD II transmitter uses a proprietary ASCII based protocol referred to as Direct Digital Access (DDA) for communication. The DDA output utilizes a 4-wire, multi-drop power and data bus RS-485 network. Utilizing the data bus network eliminates requirements for individual cable runs to and from each tank. The RS-485 network also allows for longer cable runs for more tanks and greater distances.
