CDI 5100-03S-20 Inline Low-Flow Flowmeter

The CDI 5100-03S-20 Inline Low-Flow Flowmeter extends the capability of the CDI 5000 Series to the low flow rates found in many point-of-use applications. It does this by concentrating the flow into a small area that is chosen to optimize the tradeoff between pressure drop and low-flow sensitivity. Used in its intended flow range and at a pressure of 100 psig, the 5100 will create a pressure drop no greater than one psi. The CDI 5100-03S-20 is a thermal mass design, using one probe to sense the air temperature and maintaining the other ten degrees warmer. By concentrating the flow where it passes the two probes, it is able to measure low air flows without requiring small passages that could clog or create excessive pressure drops. The meter is furnished with a 6" piece of 3/8" pipe to be installed where the air enters the meter. With the pipe in place, there are no other requirements for flow conditioning or straight upstream pipe. The meter may be installed between quick disconnect fittings to test air usage by small pieces of equipment.  The CDI Meters are designed to be used in air and nitrogen applications.  Toluene will not affect the accuracy of these meters, but a leak could pose a serious safety hazard including the risk of an explosion.  An intrinsically safe meter would be the best choice.
