Question: I have been searching for a pressure transmitter with an NSF 61 certification for my drinking water application. Does Dwyer have any recommendations? Continue reading “Ask the Expert – Series 626 & 628 Pressure Transmitters Offer Optional NSF Approval”
Every day, billions of gallons of wastewater are collected from our homes, businesses, and industries. Wastewater is exactly what it sounds like: water that has already been used and disposed of via a tub, toilet, sink, or storm drains. Because it is full of contaminants that make the water no longer suitable for use, it is collected in the sewer system and delivered to plants for treatment to make the water safe to be returned to the environment.

A hydronic system is a system designed to circulate chilled or hot water with the connections between piping and terminal units (heating and/or cooling devices). Most hydronic systems are closed and are usually made in a series loop. In addition to pipes and terminals, valves are placed in this series as a port to balance the differential pressure in the system. The balance of this type of system is often referred to as hydronic or hydraulic balancing. Continue reading “What is a Hydronic System and What is Needed to Balance it?”
Many Dwyer Instruments, Inc. electrical products are connected to the receiver and power supply with wires that are run through electrical conduits. Often, the conduit passes through multiple ambient temperature zones in the building or plant installation.
These temperature changes can cause water vapor condensation inside the conduit.
If this condensation flows into or forms in the instrument, it can create electrical shorts or lead to corrosion that can create an instrument failure. Continue reading “Condensation Issues in Instrumentation Enclosures and How to Prevent Them”
The cleaning of produced water during oil and gas production and exploration is a crucial, although costly endeavor. In the process of bringing oil and gas up to the surface from a well, several byproducts are also produced. Water is the largest of these byproducts by volume, with 882 billion gallons produced per day. This produced water contains a variety of other compounds and substances, including organic and inorganic compounds, grease, bacteria, and dissolved solids such as iron.
