Masterflex® Direct-Read Variable-Area Flowmeters, Impact-Resistant Polycarbonate, Avantor®

Masterflex® Direct-Read Variable-Area Flowmeters, Impact-Resistant Polycarbonate, Avantor®

Precision-adjusting valve for accurate, leak-free flow control.

Direct-reading flowmeters feature a calibrated scale for a specific medium—no need to convert readings to get flow rate
Constructed with durable polycarbonate frame for rugged applications
Designed with graduations in English and metric for additional flexibility

Molded of high-impact, resistant polycarbonate, these direct-reading flowmeters are supplied with scales in both English and metric units for liquid and air, all with 10:1 turndown ratios. These flowmeters has been designed to maintain maximum pressures to 100 psig and temperatures to 150 °F. Flowmeters are ideal for OEM applications.
