These metal bodied flowmeters operate using a spring loaded orifice moving over a tapered cone, to achieve a variable area meter. Flow is indicated by a magnetic follower ring under a scale on an external glass tube. The flow reading is independent of viscosity up to 200 cS.

• Works in any orientation
• Pressure up to 350 bar (5000 psi)
• Accuracy ±5% FSD
• Repeatability ±1% FSD
• Direct reading
• Relatively insensitive to viscosity changes
• Oil or water calibrated
