What is Flow Injection Analysis (FIA)? - AutomationForum
FIA (Flow Injection Analysis) is a technique with widespread application in quantitative chemical analysis. The FIA is the injection process of discrete sample solution into a continuously flowing unsegmented stream with subsequent analyte detection. Definition: A method based on the injection of a sample liquid into a continuous flow that does ...

pH measurement | Instrumentation and Control Engineering - AutomationForum
pH is a unit of measurement that describes the degree of acidity or alkali content of a solution. The pH unit is measured in terms of 0 to 14. The pH is formed from quantitative information expressed by the level of acidity or base associated with the activity of hydrogen ions. If the concentration [H +] is greater than [OH-], then the material ...

Device type: The type of device (e.g. router, switch, firewall, server, access point, etc.). Manufacturer and model number: The manufacturer and model number of the device.

Basics of Conductivity Measurement | Instrumentation and Control ...
Conductivity (G), the inverse of resistivity (R) is determined from the voltage and current values according to Ohm’s law. G = I/R = I (amps) / E (volts) Principle of Measurement : An electrolyte solution contains positive ions, each of which has a positive electrical charge, and negative ions, each of which have has a negative electrical charge.

General Technical Precautions for C&I Equipment Installation
Oil-free compressors built specifically for this need to supply the air. Air needs to be stored in the receiver after drying. Pressure gauges must be installed after the pressure reducer and on each supply line. The proper level (height) between the tapping point, transmitter, and detecting element must be maintained.

Difference Between Intrinsically Safe and Explosion-Proof - AutomationForum
Definition and Certification of Intrinsically Safe (IS) Equipment: Equipment certified as intrinsically safe (IS) by organizations like IECEx and ATEX ensures compliance to strict safety regulations. These certificates indicate compliance with strict regulations governing machinery intended for use in explosive or hazardous environments.
