Measurements and Instrumentation

Measurement and instrumentation strategies.

• Flow Measurements

Flow metering principles - Orifice, Venturi, Flow Nozzles, Pitot Tubes, Target, Variable Area, Positive Displacement, Turbine, Vortex, Electromagnetic, Ultrasonic Doppler, Ultrasonic Time-of-travel, Mass Coriolis, Mass Thermal, Weir V-notch, Flume Parshall and Sluice Gate flow meters and more.

• Temperature Measurements

Measurment of temperature - probes, sensors and transmitters.

Instruments

Devices - sensors - communicating physical properties to observers.

Instruments - Static Characteristics

Characteristics that change very slowly with time

Measurements

Measurements are required to monitor, analyze and control processes.

P&ID - Piping and Instrumentation Diagram

Schematic illustration of a functional relationship between piping, instrumentation and system components.

P&ID Diagram - Online Drawing Tool

Draw P&ID diagrams online in the browser with Google Docs.

Process Instrumentation - ISA Codes

ISA process instrumentation codes - and combinations.

Safety Signals - Recommended Colors

American National Standards Institutes schedule for safety colors marking physical hazards.

Signals - Adding Decibels

The logarithmic decibel scale is convenient when adding signal values like sound power, pressure and others from two or more sources.
