In today’s competitive industrial landscape, optimizing operational efficiency is not just about choosing the right equipment—it’s about making strategic decisions that lower long-term costs. One critical aspect of this is selecting and maintaining the right flow measurement technology. High-quality, durable flow meters serve as the linchpin for cost-effective operations, offering precise monitoring and reducing the […]

In the world of process controls involving fluids, accurate flow measurement is a critical aspect of operations. Whether in the semiconductor equipment, automotive, medical, or industrial markets, understanding the basics of flow meters is critical to ensuring efficiency and cost-effectiveness in your processes. So, let’s dive into the fundamentals of flow meters and discover how […]

Efficient flow meters not only provide accurate and reliable measurement of fluid flow rates but can also help reduce maintenance costs in the long run. When selecting a flow meter, it is important to consider its durability and reliability. Choosing a flow meter like 6000 Series flow meter from Proteus Industries Inc., that is built […]

The short answer is it depends.  If you have a low flow rate meter then it may take longer than a higher flow rate meter.  A good rule of thumb is to start with 5-10 minutes. Watch your flow readings to see if they seem higher than expected or if they are fluctuating.  With low […]

This is a critical question when it comes to flow meter performance. Ideally the meter would be mounted so that flow is along the horizontal position. In addition, if it is a paddlewheel type meter it is best if the paddlewheel is oriented vertically and not lying flat. Finally,  if you have a low flow […]

The RoHS (Restriction of Hazardous Substances Directive) and REACH (Registration, Evaluation, Authorization, & Restriction of Chemicals) standards are critical environmental and health regulations from the European Union. RoHS, established in 2003, limits the use of ten hazardous substances in electronics and electrical equipment. REACH, introduced in 2007, regulates the production and use of chemicals and their impacts on human […]

This is a very common question in regard to installing new flow meters such as the 100 Series Flow Switches, 800 Series Metering Flow Switches, 8000 Series Liquid Flow Meters, 8000XHT Series Extreme-Temperature Liquid Flow Meters, or the 8000EMR Series flow meters. The answer depends on the type of flow sensor technology employed. In this article, we will look only […]

There are several reasons why fluid temperature matters when choosing a flow meter. Temperature effects the fluid viscosity. Usually, the viscosity decreases as temperature increases and vice versa. This may affect the measurement accuracy of your flow meter unless viscosity offsets are employed.  Please see application note, Why does fluid viscosity matter when selecting a […]

Flow meters are calibrated and/or specified at the viscosity of water at around 25 deg. C.  This condition for water is considered a kinematic viscosity of 1 centistoke (cSt). In SI units this is 1 m^2/sec.  Different flow meter types react differently to viscosity. Paddlewheel flow meters have pros and cons relative to some other […]

The accuracy of the flow meter is defined as how close a reported value is to the true flow rate. The accuracy is determined through the process of calibration.  To accurately perform a calibration, a calibration stand is required.  The stand would require a reference flow meter with an accuracy better than the expected accuracy […]
