Float & Board Level Indicator
The Float Board Level Indicators are designed for an accurate, reliable and trouble free float operated technique used in large non-pressurized storage tanks.
Principle1) Guided & Direct Indication
The Float & Board Level Indicators consits of a float connected to a pointer through a rope via a set of pulleys. The pointer glides over a calibrated gauge board, positioned parallel to the tank. The float accurately follows liquid level variations in vertical direction. The horizontal float movement is restricted by two guide wires firmly anchored to tank bottom. As such, the pointer in the TOP POSITION when tank is EMPTY and in BOTTOM POSITION when FULL
2) Unguided and Direct Indication

Top Mounted Magnetic Level Switch
The Top Mounted Level Switch is an established and reliable technique in industry for single or multiple liquid level sensing and control in open or pressurized vessels. It offers trouble free service in conductive and non- conductive liquids under widely varying temperatures, pressure, liquid viscosity and corrosive conditions, Besides it provides high repeatability, and effects of shocks or variations are minimal.
PrincipleThe Top Mounted Level Switch has a simple & study construction consisting of a float and guide tube, made of nonmagnetic material to achieve un-distributed magnetic flux. The float has a magnetic system within it and moves freely along the guide tube, which contains glass encapsulated hermetically sealed reed switches, located at preset positions. Float follows liquid level and magnetically actuates reed switch at preset positions to give a change over contact. Single or multiple switching is effected through single or multiple floats as required by application. Mounted internally or extremely through a external chamber. External mounting is adopted to overcome limited space within the tank or where mechanical devices like stirrers operate or where isolation tank is required for regular servicing. It can be mounted vertically from top. The level switch can be wired directly in series to operate electrical loads like audio or alarm, annunciation, mimic indication, which match the low swtiching capacity of reed contacts. However, high loads like contactor, solenoid or motorised valve should be connected thorugh a level controller to prevent overloading by surge or inrush current and isolate reed contacts from the electrical power system, to ensure their long life.

Side Mounted Magnetic Level Switch
Side Mounted Magnetic Level Switch is an economical free and reliable device used for high, low and intermediate point level switching. It is used for tanks with inaccessible tops or bottoms and where insertion depths of top mounted models exceeded.
PrincipleThe Side Mounted Magnetic Level Switch has a compact & rugged construction, consisting of a free moving pivoted float assembly and a switch enclosure in non magnetic material to achieve undisturbed magnetic flux. It employs dual magnetics, one carried by the float arm and other by contact carries housed in switch enclosure. A change in liquid level brings the like poles of dual magnets opposite to each other and resulting repulsion force ensures a changeover of contacts with snap action. The magnetic transmission is glandless, leaving no scope for leakages from vessel into switch housing. These switches are manufactured in various materials, enclosure and special features to suit broad range of media and applications. They are designed to provide high repeatability and to minimise effects of shock, vibration and pressure.

Cable Float Level Switch
The PI Controls Cable Float Level Switch is a simple user friendly and reliable switch for liquid level detection. By selecting an appropriate float and cable length, it can be used for small or long range detection of liquids, with or without impurities, sanitary applications like drinking water and also for explosive liquids or liquids in hazardous areas. Besides this by using a number of cable floats with appropriate fixation points, it can be used for multipoint detection.
PrincipleThe Cable Float Switch consist of a float, integral with a three core electric cable. A fixed micro switch and a moving steel ball are enclosed within the float casing. A change in liquid level causes the float to tilt up or down around a pivot, provided in the form of an adjustable stopper, support pipe or ballast, at an angle and in the process, actuating a steel ball to move and operate a micro switch plunger to close or open an electrical circuit with potential free contacts, to operate auxillary electrical devices like, alarm, pump and solenoid valve.

Smart Displacer Level Transmitter & Controller
ZTD series smart displacer level (interface) transmitter (hereinafter called ZTD) is joint manufactured by PI Controls Ltd and Fisher Controls Company. ZTD-G is multi-purpose transmitter designed for measuring level, interface, or density. Having multiple function, durability, stability, and cost-effective properties, it’s welcomed by customers in petroleum line for tank, vessel or process control, etc.
Displacer Level Controller
Measuring element of displacer level controller is ball float or displacer, measuring element connected with magnet tube. When level raised, magnet tube moves up and enters external magnetic field. Through magnet induction effect or magnet coupling effect, the magnet controlling switch or offset magnet steel is pulled and makes switch contact on or off. When level goes down, the magnet tube moves down and goes out off the external magnet field. Then the magnetic controlling switch backs to the original state of the offset magnet steel goes down back to new balance position under the action of self-weight, and then makes switch contact on or off. In this way, it realizes level controlling and alarming.
