rigid compact construction dual rotatable direct reading scales for air and water graduations reflect both metric and English systems vertical in-line or panel mount versions available flow ranges from 3 to 4 LPM water and 100 to 625 SLPM air

model xV brass or stainless steel rotameter for medium flow rate measurement, with rotatable multi-gas scales in either SCFM or SLPM units

The Optical Sensor Switch Hi-Lo is a non-invasive means for detection of a HI or LOW flow. This set of sensors is ideal for signaling an alarm, cutoff valve, or other device when the float passes the detector (alarm, valve, etc. are not included). The Optical Sensor Switch helps protect processes and equipment from damage caused by extreme flow rates. Its compact design and ease of operation make it a non-obtrusive, simple to use addition to your flow meter. Perfect for OEM applications, use whenever maximum or minimum flow levels need to be monitored automatically. It also can be used in conjunction with a control relay to power alternate equipment or monitoring devices. Used in conjunction with P, S and T Style Flow Meters.
