PIC and our principals
Safety valve test: what a test bench checks and how often
Safety valve test explained: what a test bench checks, how a bench test runs, and the intervals in Malaysian law, API 510 and the NBIC.
Dead weight tester calibration procedure, step by step
Dead weight tester calibration procedure, step by step: set-up, loading the masses, floating the piston, and gravity, temperature and height corrections.
Pressure calibrator: handheld, documenting, or controller
A pressure calibrator is the reference in every pressure calibration. Handheld, documenting and controller types compared, and how to choose one.
Differential pressure transmitter: what it measures and where it is used
A differential pressure transmitter measures the difference between two pressures. How it reads flow, level and filter loss, and how to choose one.
What is a thermocouple, and how does it differ from an RTD
What is a thermocouple? How two metals make a millivolt signal, the main types and tolerance classes, and how it differs from an RTD such as a Pt100.
Types of flow meters: which one fits which pipe
Types of flow meters compared: positive displacement, turbine, magnetic, vortex, Coriolis, ultrasonic, DP and variable area, and when to use each.
How a magnetic flow meter works, and where it does not
How a magnetic flow meter works, which liquids it measures, where it fails (oils, gas, low conductivity, air) and how to install it right.
What is a pressure transmitter, and how do you choose one?
What is a pressure transmitter? How it turns process pressure into a 4 to 20 mA signal, gauge, absolute and DP types, and how to choose one.
Level transmitter types: hydrostatic, ultrasonic, radar and guided wave radar
Level transmitter types compared: hydrostatic, differential pressure, ultrasonic, radar and guided wave radar, how each works and where each fits.
