Corrosion Prevention Methods

There are some ways we can choose to protect the iron from getting corroded. The iron or any metal getting corrode because they are reacting to water and oxygen, when we can stop water or oxygen reaching the surface of the metal then we stop the corrosion process.These methods are applicable to prevent corrosion in (…)

Why Zinc Does Not Corrode As Fast As Iron

Actually Zinc (Zn) corrodes faster than iron because it is more reactive. But due to the corrosion of zinc, the reaction of zinc with water and oxygen forming substances (Zn(OH)?) that are very tight and stable. This layer ultimately acts as a coating that protects the zinc underneath because water and oxygen cannot penetrate the (…)

Windows 10 Split Screen for Engineers Work Quicker

As an engineer, you might check calculations or other works often and open several reference documents, open one and change to open another document in turn, again and again repeatedly. Uh! Very tiring and dizzy! If you have more than one monitor of course it will not happen, you can open your primary work on (…)

HMB, The Process Data for Instrument Sizing

HMB (Heat and mass balance) is a document that presents various process data variables in each stream. This document is generally producedby process design engineers while preparing a plant design plan. The HMB is presented in a table that explains the process data variables for each stream. Presentation of the HMB data is inseparable from (…)

Coriolis Mass Flow Meter Functions Instrument Engineer Should Know

Coriolis flow meters generally come with a fairly high degree of accuracy.This makes this type of measuring device as an option in buying and selling fuels (custody) or food industry applications that needs the right dose in the process. However, although many companies provide specifications for installation in their factories, we still find many of (…)

Instrumentation and Control Jobs

Instrumentation and control jobs are a pretty good career with a fairly high salary offer at the beginning of a career and get higher along with the experience they have. Its roles and responsibilities include preparing engineering designs to carry out construction and commissioning. Types of instrumentation and control jobs can be divided into several (…)

Local Control Station Wiring Diagram

The following is the Local Control Station Wiring Diagram for pumps.This diagram shows how to connect the circuit to control the pump locally and remotely. The wiring is also equipped with an emergency stop so that if an emergency occurs, the operator can activate it for safety.

Control Valve Diagram

Control Valve is a final element that is widely used in the industry. The Control Valve is used as the final element for regulating process variables such as flow, pressure, level, and temperature. Following is the control diagram of the control valve in a process control loop. Generally, the control valve is defined as a (…)

Wet Contact Relay and Wiring Diagram

This is very important to understand about wet contact relays, outside the head, for instrument / automation or electrical engineers. This is because it relates to the remote control method on many devices, almost all. Internal Wet Contact Relay on a Remote Device Below is a diagram showing an internal wet contact relay in a (…)
