TOP MOUNTING ® DESCRIPTION Magnetrol's displacement type level switches offer the industrial user a wide choice of alarm and control configurations. Each unit utilizes a simple buoyancy principle and is well suited for simple or complex applications, such as foaming or surging liquids or agitated fluids, and usually costs less than other types of level switches. Liquid Displacer Level Switches Displacer level switches for single or multiple pump control / level alarm F E AT U R E S • Narrow or wide level ranges achieved through multiple switch mechanism capability • Maximum process temperature: +260 °C (500 °F). • Maximum process pressure: 55,1 bar (800 psi). • S.G. as low as 0.4 kg/dm3. • Displacers adjustable at any point along the suspension cable. • Anti-surge design eliminates the possibility of switch short cycling. • Standard 3 m (10 ft) of suspension cable, included for all models. • Field adjustable set point and switch differential. • Wide choice of displacer materials. • Wide choice of housings and switch mechanisms • Standard anti-corrosive protection. • Optional: - NACE construction (MR-01-75) - Proof-er® ground check - Floating roof models - High pressure models - Models for interface. • Suited for SIL 2 loops (DPDT switch) (full FMEDA report available).

Worldwide level and flow solutions P R I N C I P L E O F O P E R AT I O N Standard controls Operation is based upon simple buoyancy, whereby a spring is loaded with weighted displacers which are heavier than the liquid. Immersion of the displacers in the liquid results in buoyancy force change, which moves the spring upward. Since the spring moves only when the level moves on a displacer, spring movement (1) is always a small fraction of the level travel between displacers (2). A magnetic sleeve (3) is connected to the spring and operates within a non-magnetic barrier tube (4). Spring movement causes the magnetic sleeve to attract a pivoted magnet (5), actuating a switch mechanism (6) located outside the barrier tube. Built-in limit stops, prevent over stroking of the spring under level surge conditions. Proof-er® controls The purpose of the Proof-er® is to check the operation of a displacer control without having to raise the level in the tank. This is accomplished by pulling downward on the Proof-er® cable. This causes the spring loaded lever arm to lift the switch actuator, simulating a high or high high level condition. When the cable is released, the Proof-er® returns the actuator to its previous position to resume normal operation.

The operating level is fully adjustable by simply repositioning the displacer along its suspension cable. The differential band is ± 51 mm (2") in water and varies with liquid specific gravity. Models A10 – Pump or valve control Wide differential type These wide differential units are factory calibrated to actuate as a liquid level reaches a given displacer and to remain actuated until the level reaches a second displacer. The minimum differential band is approximately 152 mm (6") in water and varies with liquid specific gravity. The maximum differential is determined by the length of the displacer suspension cable. DUAL SWITCH MODELS Models B15 Narrow differential type These instruments utilize two switches, each actuated at a different level and each calibrated with a narrow differential band. 4 Models B10 Wide differential type These wide differential tandem units are factory calibrated with a choice of several operating sequences. O P E R AT I N G S E Q U E N C E S Model B10 units are available factory calibrated with a choice of switch operating sequence. Five of the most popular sequences are described below. When ordering B10 units, an operating sequence and specific gravity MUST be provided. PUMP CONTROL PLUS ALARM Arrangement N° 1 — fill with high level alarm At the lowest level the pump starts. When the level rises to the middle displacer, the pump stops. If the level continues to rise, the upper displacer actuates the alarm switch which remains actuated until the level drops to the middle displacer. CONTROL OF 2 PUMPS Arrangement N° 4 In this sequence N° 1 pump starts as the level rises to the middle displacer. Should the level continue to rise to the upper displacer, N° 2 pump is actuated. Both pumps operate until the level is dropped to the lower displacer. Top switch, narrow differential fixed ALARM Bottom switch, wide differential adjustable PUMP Arrangement N° 2 — drain with low level alarm The sequence of arrangement N° 1 can be reversed to provide pump start at high level and pump stop at low level followed by low level alarm operation. Top switch, wide differential adjustable Bottom switch, narrow differential fixed PUMP ALARM Top switch, wide differential adjustable PUMP 2 Bottom switch, wide differential adjustable PUMP 1 Arrangement N° 5 The pumping sequence of Arrangement N° 4 can be reversed for a pump “fill” application. Top switch, wide differential adjustable Bottom switch, wide differential adjustable PUMP 1 PUMP 2 CONTROL OF 2 PUMPS OF DIFFERENT CAPACITY Arrangement N° 3 — fill or drain Two pumps are used to keep a tank filled. When the level falls to the middle displacer, a small N° 1 pump starts. A second larger pump is started should the level continue to fall to the bottom displacer. Top switch, wide differential adjustable PUMP 1 Bottom switch, wide differential adjustable PUMP 2 5 TRIPLE SWITCH MODELS Models C10 Wide differential type These wide differential type switches are designed to provide three electrically separate control signals in sequence as liquid level varies. These units are factory calibrated with a choice of several sequences.
