Dwyer, HFB-6-75, Series HF In-Line Flow Monitor, Brass, 2" Female NPT, 8-75 GPM Water
±2.5% Accuracy, Unrestricted Mounting
Low Cost, Series HF In-Line Flow Monitors have a design based on a floating sharp-edged orifice disk and variable area flow measurement to yield accuracy of ±2.5% over center one-third of scale. This unique design allows accurate performance with fluid viscosities up to 500 SSU. All internal wetted parts are contained inside a sealed metal tubular casing assuring a virtually maintenance-free unit. Flowing media forces linear motion of a spring loaded, sharp edge orifice disk and ring shaped transfer magnet which both ride on a tapered center shaft. The transfer magnet drives a clearly visible magnet follower located outside the flow tube, protected under the clear polycarbonate tube. A ring on the magnet follower indicates flow rate on the direct reading scale. Rubber bumpers are provided for external impact resistance.
Designed for single-direction flow, Series HF Monitors are recommended for use with system filtration of at least 74 microns or a 200 mesh screen. Some applications may also require magnetic filtration. These flowmeters do not require inlet or outlet straight plumbing and can be mounted horizontally, vertically, or inverted.
Product Applications
- Used to set flow rates, fluid motor and cylinder speeds.
- Check pump high pressure performance, pressure relief valve settings, fluid handling systems in agricultural, construction or industrial machinery, power tools and equipment.
- Monitor petrochemical operations with brass or stainless steel models.
- Industrial pneumatic systems air flow can be monitored with the HFA models which are calibrated at 100 psig inlet pressure.
