Measurements & Instrumentation
Measurement and instrumentation strategies.
• Temperature Measurement
Measurment of temperature - probes, sensors and transmitters.
• Flow Measurement
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.
Devices - sensors - communicating physical properties to observers.
Instruments - Static Characteristics
Characteristics that change very slowly with time
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.
