Principle of Operation
The Masoneilan 12300 series instrument is a 2 wire, loop-powered Level Transmitter or Controller with HART Communication, that operates according to the fully proven buoyancy and torque tube principles. A change in liquid level varies the net weight of the displacer (130), increasing or decreasing the load on the torque tube (136) by an amount directly proportional to the change in liquid level. The resultant rotation of the torque rod (138) and attached magnets (140) modifies the magnetic field surrounding a Hall effect sensor (141), producing an analog signal proportional to the level in the vessel. This analog signal is converted into an error-free digital signal that is processed by the on-board microcontroller. After processing, the digital result is converted to a 4-20 mA analog output signal. This sensing method is non-contacting, frictionless and provides total isolation between the sensed motion and sensor output.

General Description
The Masoneilan 12300 Series Instrument is a digital level Transmitter or Controller with HART communication. This high performance instrument is easily set-up and calibrated by use of either the Masoneilan ValVue software or a handheld communicator or local push-buttons with a digital display. This versatility permits the users to perform calibration, configuration of alarms... without ever leaving the control room. This instrument does not need a separate power supply and offers the following :
Proven technology The highly system has because of most severe reliable displacer/torque tube been very popular for decades its excellent features under the conditions :
Smart features Smart filtering : Unwanted oscillations can be eliminated through the use of an adjustable smart filter. This smart filter does not damp or delay response to fast level changes. Adjustable low and high level alarms. Adjustable failsafe output signal. Continuous data recording : number of filling up, high level time, low level time, working time, ... Software ambient temperature compensation.
Installation flexibility Requirements of almost every installation are met with top, side or bottom connections and a full rotation in the horizontal plane to accomodate process structures - Continuous level transmission and wide process temperature range : -210C to +450C - Excellent stability When installed inside a chamber, surface turbulence and foam do not impede the d i s p l a c e r. M o r e o v e r, m e a s u r e m e n t i s uneffected by agitation of the process fluid. Simple calibration and set-up
Outstanding characteristics The design of the 12300 instrument offers the following performance features : Dual compartment case isolating process pressure from main compartment. Non-contacting, frictionless sensor offering 0.1% resolution of measurement. No effect on calibration with ambient temperature variations. Compensation of thermal differential expansions by the torque rod mechanism. High degree of wheather protection. Protected from dust, rain, snow, water jets, limited submersion and corrosives atmospheres. Last configuration and calibration data are always stored in a non volatile memory, even in the event of a power failure.
The following functions provide significant timesavings during calibration and configuration : - Calibration with or without fluid - Independent, non-interactive zero and span adjustments - Zero shift and/or reduced span adjustment, even with empty chamber - Measurement of the liquid level of a fluid with unknown specific gravity Level controller
Retrofit The 12300 level controller is a full featured process controller. Its 4-20 mA output signal controls the control valve positioner to automate level applications. Additional features include : Advanced control, remote setpoint control and level transmission using the HART protocol. Retrofit of older electronic and pneumatic level transmitters or controllers is accomplished by replacing the housing sub-assembly. In some cases, replacement of the torque tube is also required. Retrofit of duplex pneumatic cases is also achievable with 12300 instruments associated with SVI positioners.

Mounting
Model 12303
Model 12304
In case of internal mounting, the instrument has no displacer chamber ; the mechanism chamber flange is bolted directly on the vessel flange. In case of liquid turbulence, it is recommended that the displacer is isolated with a damping chamber to prevent oscillations.
Model 12300 Model 12301
Model 12309 Model 12302
Model 12305 Model 12308
Model 12306 Model 12307
In case of external mounting, the instrument is connected to the vessel either with flanges or with screwed or welded connections. The instrument is constructed so that the mid range level reference on the displacer chamber coincides with the normal level in the vessel. It is recommended that shut-off valves are inserted between the level connections and the vessel, with a drain valve on the lower part of the level.
