Flowmeter PTFE/Sapphire (CP/P-03266-55)


RM 1,749.00


Designed for high-purity applications with flexibility for a broad array of gases
  • Correlated flowmeters feature a generic scale—reference flow curves calibrated to a variety of media, temperatures and pressures to get the flow rate│Use with a variety of media for laboratory and industrial applications


The substitution of metal fittings with PTFE eliminates a potential contamination source for high-purity applications. The glass tube utilizes a fused ceramic scale for a precise, permanent measuring guide. In addition, a vertical-tangential locator line provides readings with hairline accuracy. Further improving readability is a front shield that magnifies the scale 16%. An anodized aluminum frame protects the heavy-walled glass flowtube; a white acrylic backplate protects and enhances viewing in the protective frame.

Select a flowmeter with a valve for flow rate control. The standard valve is suitable where high resolution metering is not essential. The high precision valve features a fine-adjust 16-turn “non-rising stem” to more accurately set your desired flow rate.

All flowmeters come with correlation data sheets for water and numerous gases (listed below) at standard temperature and pressure (STP).
