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 that is built to withstand the demands of your application can minimize […]
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 […]
ROHS and REACH originated in the European Union in 2003 and 2007 respectively. ROHS (Restriction of Hazardous Substances directive) restricts the use of 10 hazardous or potentially hazardous elements used in the manufacture of electronics and electrical equipment. There are a few exceptions. REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) deals with the production […]
This is a very common question in regard to installing a new flow meter. The answer depends on the type of flow sensor technology employed. In this article we will look only at paddlewheel type flow sensors. With this type of meter, the inlet is the most sensitive and critical to the performance of the […]
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 […]
The RoHS (Restriction of Hazardous Substances Directive) and REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) standards originated in Europe to specify and identify chemicals and other materials used in manufacturing that are environmentally harmful. These are required certifications for any company shipping products to the EU and Great Britain and, the standards have been […]
