URL Variable Area Flowmeter
Brand: KOBOLD Instruments, IncThe Kobold URL model flow meter/monitor works on the basis of the suspended float principle. It is used for measuring the flow rates in closed pipe line systems. The medium flows from below through a glass measuring cone that gets wider on top.
Thus, the float is raised and indicates the respective flow rate on the scale provided on the measuring cone.
To monitor flow rate limits, the URL meters can be optionally furnished with "open collector" proximity switches.
This plastic version is not only economical but also resistant against several chemicals. By its special design, this model is particularly suitable for applications where only very small operating pressures are available.
Another advantage is offered by the very large sight glass which optically allows direct flow observation.
