How to Choose a Flow Meter for Low-Flow Applications: A Practical Selection Guide Direct Answer Choosing a flow meter for low-flow applications requires matching the instrument’s measurement principle and calibrated range to the actual minimum, normal, and maximum flow rates. Fluid properties, required accuracy, turndown ratio, pressure drop, operating pressure, temperature, and installation conditions must…
How to Choose a Flow Meter for Corrosive Liquids: A Practical Selection Guide Direct Answer Choosing a flow meter for corrosive liquids requires matching the meter’s measuring principle and wetted materials to the chemical composition, concentration, operating temperature, pressure, and flow characteristics of the liquid. Chemical compatibility should be verified before comparing accuracy, price, or…
How to Choose a Flow Meter for High-Viscosity Liquids Direct Answer Selecting a flow meter for high-viscosity liquids requires evaluating the fluid’s viscosity at its actual operating temperature, the required flow range, allowable pressure drop, fluid cleanliness, and measurement accuracy. Positive displacement flow meters, particularly oval gear flow meters, are often suitable for clean, viscous…
1. Direct Answer The appropriate level meter for an oil tank depends on the oil properties, tank structure, operating conditions, required measurement accuracy, and installation environment. Common options include non-contact radar level meters, guided wave radar level transmitters, hydrostatic level transmitters, and float-type level instruments. For continuous level measurement with minimal direct contact with the…
How Air Bubbles Affect Flow Meter Accuracy Direct Answer Air bubbles can significantly affect flow meter accuracy when measuring liquids, but the extent of the error depends on the measurement principle, bubble concentration, bubble size, flow conditions, and installation configuration. Entrained air can cause unstable readings, measurement deviations, signal loss, or incorrect totalized volume. The…
Electromagnetic vs. Vortex Flow Meter: How to Choose the Right Technology Direct Answer Electromagnetic and vortex flow meters are designed for different measurement conditions. An electromagnetic flow meter is generally the better choice for electrically conductive liquids, especially water, wastewater, chemicals, slurries, and other liquid applications where low pressure loss and no moving parts are…
how to increase oval gear flow meter flow range ? A Practical Guide to Flow Range and Sizing Direct Answer If by “increasing the parameters” of an oval gear flow meter you mean measuring a higher actual flow rate, this normally cannot be achieved simply by changing the display or software settings. An oval gear…
Can Target Flow Meter Customization for Special Working Conditions? Direct Answer Yes. Target flow meters can generally be customized to match specific process conditions, especially when standard flow meter configurations cannot adequately match the medium, flow range, pressure, temperature, pipe size, connection, or installation requirements. Unlike selecting a flow meter only by nominal pipe diameter,…
How to Select a Flow Switch for Water, Oil, and Hydraulic Systems Can a Water Flow Switch Be Used for Hydraulic Oil? One of the most common engineering mistakes in industrial flow monitoring is assuming that a flow switch calibrated for water can be directly applied to oil or hydraulic systems. This can result in…
Why Mechanical Flow Switch Failure in Oil Systems? Mechanical vs. Thermal Flow Switch Why Do Mechanical Flow Switches Fail in Oil Systems? Direct Answer Mechanical flow switches can stick, seize, or generate false alarms in lubrication and hydraulic oil systems because their operation depends on moving mechanical components such as paddles, pistons, springs, or magnetic…
Thermal Flow Switch Principle & Applications Direct Answer A thermal dispersion flow switch detects the presence, absence, or specific velocity of liquid or gas flow by measuring how flowing fluid removes heat from a heated sensing element. The sensing probe typically contains a reference temperature sensor, a heated sensor, and an internal heating element. As…
