Prepared by Ken Mease, this powerpoint presentation held at the Workshop on Governance Assessment Methods and Applications of Governance Data in Policy-Making (June 2009), looks at indicators more closely, and discusses definitions of indicators, macro and micro levels for constructing indicators, different advantages of de jure and de facto indicators, triangulation, indexes versus scales, objective indicators such as reported behaviours and events, perception based indicators such as opinions, and proxy indicators.
Propane Gas Level Tank Indicator (GLI) theoryJohn Romano
.The GLI is a highly sensitive thermometer that measures the temperature change on the outside of the tank caused by evaporation
.The temperature difference causes one or more of the columns on the GLI to change color right where the tank changes temperature.
.The liquid level is shown precisely where the column on the GLI changes color.

This project uses a temperature sensor to detect the occurrence of a fire and in that case uses a GSM module to send a text alert to the user's phone number.
Mostly and must needed equipment for water tank in our house or industry. Water level indicator not only indicates the water level but also switch OFF and ON the power supply to water pump automatically. Most Demanded and easiest project to built. Can be constructed by beginner.
It is a simple innovative idea which demonstrates how to design a simple circuit which can act as a WATER LEVEL INDICATOR. It is a general idea and can be even modified to build an AUTOMATIC ON/OFF CIRCUIT as the water starts overflowing by implementing a simple JK-flip-flop in the circuit.
