• Automatically monitor flow rates within a high/low band

• Protect your equipment from damage caused by extreeme flow rates
• Features dual-mounted LED receiver/sensors with optical sensors

These 150-mm valved flowmeters feature two noninvasive optical sensors that easily glide up and down both sides of the meter to set high and low flow rates. The meter is ideal for use with an alarm, valve, or other devices to control flow with use of NPN and PNP transistor oputput. The compact design and ease of operation make this meter perfect for laboratory and industrial uses.
