Most analog output sensors have general specifications such as linearity (or non-linearity), repeatability, and resolution, as well as environmental specifications like operating temperature or shock and vibration, and dynamic specifications like response or bandwidth.
Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odours. In the sequencing batch reactor (SBR) process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.
For some time now, automation vendors have been promoting anytime, anywhere access to your process data, but delivering on the promise has been technically and commercially challenging to scale. Now that this actually is within reach, you may be suspect.
Level indicators can be incredibly versatile, but what all can they be used for? Below are some examples of applications for level indicators.
A hot rolled steel manufacturer was encountering problems with moisture in their air lines causing instrumentation failure and premature maintenance requirements.
There are three methods of measuring pressure. The most common type of pressure measurement is gauge pressure, with reference to atmospheric pressure. This is any pressure applied to the system on top of atmospheric pressure, also known as ambient pressure.
Midstream oil and gas companies can’t afford unplanned downtime. Studies have shown unplanned downtime can costs tens of millions of dollars per year in lost productivity and repairs, on top of the physical risks involved when equipment fails.
With mid-sized and micro-breweries popping up all around the world, uneven water pressure and a never-ending variety of floorplans are creating headaches in the final rinse stations during the bottling and canning process.
Specifying the proper pumps in mine dewatering applications is critical to avoiding stalling and loss of production. In this example, a company was using 2-inch air-operated double-diaphragm pumps (AODDs) for its mine dewatering application at their gold mine site.
With COVID-19 reducing in-person access to energy plants around the world, Ecolab is using new digital solutions to deliver its water, energy and sanitization solutions.
