Basic Electronics For Field Measurement

Measurement technicians deal with electronic flow computing and field devices daily. Most of the field instrumentation are tightly integrated in a complete system with interdependencies on several different electronic products. The larger the metering station, the more complex the system.

Basic field duties related to electronic instrumentation would include:

Some of into and out of the device. Each of these play unique circuitry roles and require different knowledge of their intended operation.

the basic types of connections and measurements include power as well as analog signals and digital signals going

Fluid Flow Analogy and Ohm’s Law

Electricity has three components: voltage measured in volts (equivalent to pressure in a fluid piping system), resistance to the flow, measured in Ohms (equivalent to pipe roughness) and current, measured in amps (equivalent to the fluid (gallons of water)). Ohm’s law is the mathematical relationship between voltage, current, and resistance. Given any two of these values you can calculate the third. The units of measure include V for voltage (Volts), I for current (Amps), R for resistance (Ohms Ω).
