Miracle electronic devices has developed latest generation fuel level monitoring and controlling system [mlc], which is a safe and sophisticated gadget for automatic monitoring of generator`s fuel tank. Mlc fuel level monitoring and controlling systems are available with salient features like solid-state electronic device for use with fuel level dial indicator and fuel tank float sensor; 12v dc supply; entire circuitry raised in metal enclosure with powder coating for better life; with an anodised aluminium front panel and imported polycarbonate panel sticker; any other plc or other circuit arrangements to give audio-visual warning purpose and output signals; two user accessible settings, one for settings can be done at site also; setting points placed on front panel and marked with hlf and lfl respectively; three visual indicators on front panel, one for indicating power on, second for half level and third for low level; and outputs accessible by terminal block to provide terminal identifications. The company supplies these fuel level monitoring and controlling systems that are fitted on panel by screws. These fuel level monitoring and controlling systems are useful for any capacity r generators and for any fuel tank. These fuel level monitoring and controlling systems [mlc] come with technical specifications like 12v/24 v dc ± 20% voltage supply; less than 25 ma current consumption; npn semiconductor type [active low] outputs; 100 ma maximum output current; power on, half low level and low level output indications; and low level and half level set tings.
