How does a float switch work?
When it comes to measuring liquid levels in tanks, few instruments are as reliable as the float switch. So how does a float switch work?
How-to Prevent “Freezing” of Latching Valves in Extreme Cold
During winter months and in extreme cold conditions, valve malfunctions can occur that can be extremely inconvenient and expensive. When malfunctions occur in these climates, users typically cite freezing of valves as a cause. However, tests have shown that this is perceived “freezing” and can in fact be prevented.
What is a Flow Meter?
A flow meter measures both conductive and non-conductive fluids, as well as gases and can be used to totalize or monitor the rate at which media is flowing through a given space.
What Is An Integrated Sensor?
An integrated sensor is the core technology of a sensor without the package and allows for multiple sensor technologies to be combined into a single assembly.
5 Types of Pressure Sensors You Should Know
Just like a drill won’t work with a nail, the type of pressure sensor you’re using for a given application matters. What performs well when measuring oil and gas, for example, may not be the best fit for hydraulics.
What’s the Difference Between Continuous and Point Level Sensors?
In order to measure the amount of a fluid in a given container, many opt to use a level sensor. But what kind of level sensor is right for your application?
