Flowmeters Manual & Mass Flowmeters

flowmeter is a simple and precise way to measure flow rates of gases. It is the most common device for measuring a volumetric flow rate. This unit has a buret of appropriate volume fitted with rubber bulb at the bottom and a side arm. Air is passed into the buret and the bulb filled with soap solution is squeezed. This causes a soap bubble to enter the buret. The time taken for the bubble to travel in considered as known volume, used to calculate the flow rate. The most basic configuration of a flowmeter is a calibrated tube, a stopwatch, and a good eye

The operating principle of a mass flowmeters is basic but very effective. This phenomenon is all around us in the physical world; for example the earth’s rotation and its effect on the weather.

A mass flowmeters contains a tube which is energized by a fixed vibration. When a fluid (gas or liquid) passes through this tube the mass flow momentum will cause a change in the tube vibration, the tube will twist resulting in a phase shift. This phase shift can be measured and a linear output derived proportional to flow.

• Mass Flow Rate, Volume, Density and Temperature Measurements
• Rugged Meters with No Moving Parts Results in Minimal Maintenance
• Accuracy Over a Wide Flow Range From a Single Meter Optimizes Plant Efficiency
• No Flow Conditioning or Straight Pipe Runs Required, Making Installation Simplified and Less Expensive
