What Is Draft:
Draft means a difference in pressure or differential pressure. The word draft is usually used for very low-pressure differentials up to 1000 mmwc. It is measured with the help of a transducer that converts this small differential pressure to a small electrical signal. This signal, in turn, is amplified to standard values like,
4 – 20 mA, 0 – 5.0 Volts, etc., and then used for display as well as control.August 7, 2021
In this series, we shall see the principles of operation of various types of flow meters. First, we will discuss the principles of different types of Mass Flow Meters and later the principles on which the volumetric flow meters are based.April 20, 2021
Mass flow and Volumetric flow – When to measure?
In the last article, we discussed how it is important to measure fluid flow. Here we will have a look at the difference between mass flow and volumetric flow. We will also discuss when to check the mass flow and when volumetric flow measurement is sufficient.March 25, 2021
Can solids flow?
It is usually said that flow can occur only when the substance is having fluidity. The solids like powder, coal stacks, etc. are not having fluidity, obviously, flow cannot occur for such substances.January 2, 2021
