Dave Korpi here, in Pacific Grove California.

I make thermal mass flow meters and they are not happy with abrasive slurries. It is better to use delta p devices or ultrasonic mass flow meters to protect this type of slurry pump. If you have a big budget folks may choose Coriolis meters because they have extraordinary accuracy and have nothing protruding into the flow in most designs. Delta P devices with converging/diverging with pressure recovery sections are also ideal as well.

Thermal mass flow meters are happiest with clean dry gases. The reason is they “care” about the thermal conductivity of the material. If the material is not dry this parameter is not constant.

So… if you need to measure clean gases then call on the thermal dispersion or thermal mass flow meter guys… And we will do as they do.. Tell folks about the ideal applications and where NOT to use them as well as where to use them..

Thanks,

Dave Korpi

Power monitors usually will refer to a recording or display device that shows electric loads either instantaneously or over a period of time.

They should not be confused with a Power Quality Recorder, which can do the job of a power monitor, but can also provide useful information for troubleshooting electrical problems.

Valve actuators are really needed for complex tasks in the high power market.If the load requires accurate positioning, the electric actuators as well as the valve actuators has the advantage among others.That is why,to familiarize yourself in this kind of industrial application , knowing how an automation works is a wisely action and will positively keep us in track.

More complex control systems using valves requiring automatic control based on an external input require an actuator. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements.
