At JLC International, we distribute many different kinds of flow meters for multiple types of industries and uses. Of which we are able to provide two different inline small bore ultrasonic flow meters:

  • Light-Duty Ultrasonic Flow meter Atrato Series 700
  • Industrial Ultrasonic Flow meter Atrato Series 70P

This technology allows for an astonishing accuracy over very wide flow ranges across the whole span. With a rugged, clean bore construction, the Atrato flow meters are perfect for a wide-range of low flow applications. Furthermore, the USB connection of the Atrato flow meter allows monitoring the rate and total directly on a laptop for convenience and ease of use. One can alter the operating parameters for pulse resolution and units. This can make utilization of this flow meter a much easier task.

Time of Flight Measuring System

The measurement of the low flow rates of liquids in small tubes is very hard with conventional transit time ultrasonic techniques for multiple reasons. If a diametrical beam is used, the defining equation for the transit time difference between the upstream/downstream directions has a constant proportionality, which includes the diameter of the tube. Therefore, as the tube diameter becomes smaller, the transit time difference for the given velocity becomes proportionally smaller.

The Atrato flow meters use a time of flight measuring system that measures the upstream and the downstream flight times. Half the difference is the velocity of the fluid. This patented system is capable of measuring these time differences with an accuracy that is better than 250 picoseconds. Since the pipe geometry is known, the pulse output will be accurate for the volume passed. It is enhanced even further by the primary signal to noise ratio, typically at 2000:1, but ranging higher to 3000:1.
