Why Mass Flow reference conditions matter

November 12, 2019By Daniel PregrassoUncategorized

You would think that measurements of mass flow would be expressed in units of mass, such as grams/hour, milligrams/second etc. Most users, however, think and work in units of volume. That’s OK, at least when we are talking about the same reference conditions. Let me start with an example: Mass versus Volume Imagine you have … Read More

Temperature is the most widely measured value in process control. Across a wide variety of industries from large-scale chemical manufacturing to small labs, accurate temperature measurement is relied upon to ensure such things as yields, quality, safety and compliance. The most common methods of measuring temperature in an industrial process are by either thermocouple or … Read More

Overflow Protection Made Easy

November 7, 2019By Daniel PregrassoUncategorized

Application Note Reliable and repeatable level control is critical in order to prevent contamination of the process upstream or downstream. The acid must not be allowed to flow into the process except when required as a chemical additive. What is the customers problem? Prior to the Kayden switch, the customer tried a competitors thermal switch … Read More

The most used accessory in flow control

October 29, 2019By Daniel PregrassoUncategorized

A control valve is used to control a flow by varying the size of the flow passage as directed by a signal from a controller, such as an on-board PID controller in a flow meter. It is one of the most used accessories in flow control. An accessory for mass flow controllers Control valves can … Read More

October 25, 2019By Daniel PregrassoUncategorized

The Fundamentals of RTD temperature sensors An RTD temperature sensor is a common device for temperature measurements in a wide range of industrial applications. In this article, we take a look at how they work, the most common types, and their advantages and disadvantages. The acronym “RTD” stands for “Resistance Temperature Detector”. Typically, RTDs contain … Read More

Why the rising water stress levels need to be addressed

September 26, 2019By Daniel PregrassoABB News

The summer of 2019 has brought new temperature records to Europe and North America. Earlier this month (August 6) the World Resources Institute (WRI) published an alarming report: a quarter of the worlds population faces extremely-high water stress, a situation in which the water resources in a region or country are insufficient for its needs. … Read More
