  • How Does a Water Flow Meter Work?

    A water flow meter works by measuring the amount of water that passes though the flow meter. The most common mechanical types work by measuring the speed of flowing water that causes a turbine or piston to rotate. The volumetric flow rate of the water is proportional to the rotational speed. Other water flow meters include ultrasonic, magnetic and vortex flow meters. The best type of water flow ...

  • Sensor Probe Insertion/Retractor Simplifies Installation of Steam Flow Meters in Hot Tapping Applications

    Accurately measuring fluid flows like steam in large ducts or pipes is a challenging application. Large ducts and pipes often have swirl or turbulent flow which makes accurate flow measurement difficult. Not to mention, installation of steam flow meters can be extremely challenging since in many cases you will need to shut off the steam flow to install the meter. This is just not ...

  • Tuning Your Boiler for EPA Boiler MACT Compliance

    The EPA’s Boiler MACT regulations are heating up. Boiler MACT is an EPA rule to limit hazardous air pollutants (HAP) from commercial and industrial boilers and process heaters. Originally proposed in 2011 as a mandate driven by the Clean Air Act,  the rules are Area Source Boiler MACT 40 CFR 63, subpart JJJJJJ for smaller boilers (stores, hotels, apartments, ...

  • Introducing ozone to water purification – Case Study

    Traditionally, chlorine has been used to disinfect water for drinking. Unfortunately, chlorine produces carcinogenic by-products called trihalomethanes (THM’s) when it reacts with organic substances in surface waters. The recent adoption of the Surface Treatment Rules by the U.S. E.P.A. places strict limits on chlorine. Because ozone produces fewer disinfecting by-products, the EPA, along ...

  • Controlling the addition of Chlorine into a Process

    There are several methods for controlling the addition of chlorine into a process. These methods include flow proportional injection, ORP (oxidation reduction potential) or a residual chlorine analyzer. Each method measures a different process characteristic. Depending on the specific type of process being controlled, there generally is a best choice for controlling the injection of either ...

  • Facility reduces process downtime – Case Study

    A facilities subcontractor for Boeing required meters to monitor the make-up air mass flow rate into a painting facility. The make-up fans ensure compliance with OSHA and Boeing air quality standards by reducing contamination and airborne particles that result from over-spray. The Boeing standard dictates a minimum airflow of 125 SFPM to the paint booths. Should the airflow drop below this ...
