Nowadays, gas pipeline projects are extensively implemented in advanced technological industries like industrial gases, petrochemical engineering, medicine, micro-electronics, semi-conductors, solar photovoltaics, laboratories and institutes. Mass flow gas meters are commonly applied in such projects. Centralized pipeline supply of industrial gas is a simple and efficient supply mode. However, due to…
Before talking about PM2.5, let’s have a look at the concept of PM10. In the air we are breathing every moment, there are plenty of particle matters which are named as Total Suspended Particulate(TSP). TSP is a major component of air pollutants, the ones of which with their diameter below…
Hydrogen chloride (HCl) is a diatomic molecule, consisting of a hydrogen atom H and a chlorine atom Cl connected by a polar covalent bond. It is a colorless gas with pungent smell, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrochloric acid is a solution…
What is an ultrasonic sensor? An ultrasonic sensor uses a transducer to send and receive ultrasonic pulses. These pulses relay proximity information of relevant matters, so that the sensor can output its distance to the matter. How do ultrasonic sensors work? Ultrasonic sensors transfer ultrasonic signals to other energy signal…
