HART Communication
is an early implementation of Fieldbus, a digital industrial automation protocol. Its most notable advantage is that it can communicate over legacy 4-20 mA analog instrumentation wiring, sharing the pair of wires used by the older system.
- Regardless of the age or capability of your control, safety or asset management system, HART technology can provide additional information to help extend time between shutdowns, lower maintenance cost and improve process performance.

Article - Wired vs. wireless in utility markets
My Conclusion-
In short, it is my personal opinion that wireless technology be used as a last resort. There is nothing more annoying than fighting with your wi-fi equipment because you suddenly lost your signal when you were trying to put in a last second bid on ebay, or check an important email before you walk out the door or lost communication due to bad weather etc.
Speed, Security and reliability will be never better with wireless signals that over the wire.

1. Positive Displacement (Quantity Meters) - Some of the more common positive displacement meters are: Weighers, Reciprocating Piston, Rotating Piston, Nutating Disk, Sliding and Rotating Vanes, Gear and Lobed Impeller, and the meter most commonly used to sell small quantities of gas at relatively
low flow rates, the Bellows meter.

Instrumentation Common Questions -3
I for Instrumentation
Q: What are Analog Input/output & Digital Input/output?
4-20 mA signals from instrument (transmitters) are analog input to control system.
4-20 mA signals to instrument (I/p & electro pneumatic positioner) are analog output from control system.

I for Instrumentation
Q: What is potential free contact? What is the significance and application of this contact?
Contacts having not potential. E.g. Relay contacts/ field switches contacts. They are used in logic circuits. A potential free contact is usually wired into an electrical circuit. However it must be ensured that the contact ratings are suitable for the service in which it is used.

EPC School 2012 Series
Q: Why do we use pipelines for transmitters in steam service and tubes in any other service?
A) Pipe as well as tubes can be used for steam line transmitters. However pipe walls being thicker provide more corrosion allowance. B) For steam services, with high temp and pressure needs IBR standard. Max. Working pressure is 153 kg/cm2 at 38 degC for 1/2” O.D tube as per design standard. So tube is not suitable.
