Mass Flowmeter 4226


Product Details

This unit has been discontinued as of December 31, 2007. 

Model 4226-01-01 mass flowmeter is high accuracy air flow flow rate sensor.

It features a very low pressure drop, wide flow rate range and 20 millisecond response time. The rugged, sealed housing is ideal for demanding environments.

Series 4200 flowmeters are 100% calibrated and completely ready to install. The standard, simple design of Series 4200 flowmeters saves engineering time, reduces costs and helps get products to market faster.

Note: These meters are designed and priced to be replaced rather than recalibrated. TSI does not offer recalibration of these meters.
