MAX FLOW SIZES FROM 3 to 20 GPM (10 TO 80 LPM) MAX LIQUID PRESSURE FROM 100 PSI (6.9 BAR) to 200 PSI (13.8 BAR) Flow meters, Flow switches and Flow transmitters A Small Vane-Style For Corrosive Fluids CSA Certified NRTL/C CE Marked (as noted) NIST Traceable Calibration Certificate Available DESCRIPTION These variable-area flow meters have a spring-loaded swinging vane. Mounting is in-line and in any position. Straight pipe runs before or after the meter are not required. The all-mechanical sensing system directly drives the pointer and remote signaling devices. CALIBRATION All flow meters are individually calibrated for fluids with the viscosity you specify (up to 3000 SSU (650 Centistokes). We compensate for your fluid's specific gravity. For NIST Traceability please consult factory. OUTPUTS The flowmeter has outputs both visual and electronic. Visual displays are either pointer (with inscribed scale) or numeric. Signal outputs can be mechanical switch closure, 4-20 mA analog or both SX shown with "A" style control box. (for signal redundancy). The switches can be general purpose or rated for hazardous locations (all classes, groups and divisions). The 4-20 mA transmitters are Intrinsically Safe if used with approved barriers. CONSTRUCTION MATERIALS These flowmeters have plastic bodies, a wide variety of metal internals, and fittings. They are ideally suited to monitor flows of such fluids as corrosive liquids, seawater, deionized water, acids,caustics, and plating solutions. See selections in the “How to Order” section. LINE CONNECTION Threaded units have a 7/8-14 inch SAE ports. Adapters are used to offer NPT port connections both male and female and in plastic or 316 SS (see “How to order” section). One inch diameter Van Stone flanges are offered in PVC. Fluid enters at A, passes around the semi-circular vane B, exits at outlet C. The vane resists the flow because of the spring D. The further the vane is pushed the larger the passageway E becomes. This minimizes the increase in pressure drop. The vane shaft turns to operate the pointer F and remote signal devices such as the switch G. Viton® and Kalrez are registered trademarks for DuPont Performance Elastomers. SX Series

ENGINEERING DATA Maximum fluid temperature: PVC housing: 100°F (38°C) Polysulfone housing: 200°F (95°C) Tefzel housing: 200°F (95°C) Installation Flow monitors mount in-line and are typically supported by rigid pipe. For additional support when using tubing or flexible hose, order special options W (wall) or F (foot) mounting brackets. MOUNTING BRACKETS Maximum ambient temperature: 130°F (55°C) (UL listed to 105°F (40°C); for hazardous locations -13 to +104°F.) Maximum operating pressures: (3:1 safety factor) PVC housing: 100 PSI (6.90 BAR) Polysulfone housing: 200 PSI (13.79 BAR) Tefzel...

CONTROL BOX SELECTION GUIDE “A” box is selected for price and simplicity. It holds switches (general purpose and hermetically sealed) or 4-20mA transmitter. You get this control box when you order any CONTROL BOX & READOUT starting with an “A” (see "How to Order" page). Examples: A1WR is a one switch, weatherproof box with flow from left to right. This control box is made of Polysulfone (standard low cost “A”) with options for aluminum (“L”) or 316 stainless steel (“Z”). R5.12 [130mm] APPROX. SWING RADIUS Maximum installation dimensions “R” box is selected for greater resolution (more...

CONTROL BOX SELECTION GUIDE “T” box is selected for availability of two isolated junction boxes with terminal strips. This means that no direct wiring to switches or transmitters is required. Digital LCD display of flow is optional (“TXL”). It holds switches (general purpose) and 4-20mA transmitter. Switch (standard service) and transmitter are offered in this control box together when signal redundancy is desired. These are wired to separate junction boxes for signal isolation. You get this control box when you order any CONTROL BOX & READOUT starting with a “T” (see "How to Order" page)....
