MAX FLOW SIZES FROM 500 TO 1500 GPM (2000 TO 5600 LPM) MAX LIQUID PRESSURE 300 PSIG (20.69 BAR) XHF SERIES UNIVERSAL Flow Meters ® An Extra-Large Vane Style For Liquids 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 are not required on the 4-inch meter. The meters require 2 pipe diameters straight run before and after the meter. The all-mechanical sensing system directly drives the pointer and remote signaling devices. They handle shocks or flow surges beyond their rated capacities. The swinging vane can be manually operated with a factory supplied wrench to verify or adjust switch points, or to free the vane should it become lodged by debris in the fluid. CALIBRATION All flow meters are individually calibrated on fluids suitable to maintain the stated accuracy for viscosities up to 3000 SSU (650 Centipoise). We also compensate for specific gravity. For NIST Traceability please consult factory. CONSTRUCTION MATERIALS The meter body, moving parts, and seals are offered in a variety of materials to suit a wide range of applications: water, synthetic and petroleum based oils, paint, some corrosives, solvents, and air and gases. The flowmeter body is made up of the “center section” which is where the moving parts are. Sometimes it is cost effective to match this to other materials for the in and outflow sections of the meter body and flanges. See selectiohns in the “How to Order” section. Please consult the factory for compatibility of materials with your application. 1 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 pressure drop. The vane shaft turns to operate the pointer F and remote signal devices such as the switch G.

SERVICE Weatherproof (Type 4) = W Weatherproof, corrosion proof (Type 4X) = X FLOW DIRECTION Left to right = R Right to left = L Up = U Down = D SPECIAL OPTIONS High-temp- 400°F for A & R Box, 300°F for transmitter options Stainless steel ID tag for customer supplied information Pin connector (See explanation for special options.) Tempered glass window SWITCH SETTING No symbol = Lowest possible setting (usually 10% of maximum flow) Desired set point is assumed to be in flow units already selected (GPM). Give flow rate 5ØD followed by a “D” for flow going down (flow failure) or a “U” for...

CONTROL BOX SELECTION GUIDE Standard Offering: Control Box “R” “R” box is selected for greater resolution (more increments on the inscribed scale). It holds switches (general purpose and hazardous location all classes groups and divisions) and 4-20mA transmitter. Switch (standard service) and transmitter are offered in this control box together when signal redundancy is desired. You get this control box when you order any CONTROL BOX & READOUT starting with an “R” (see "How to Order" page). Examples: R1WR is a one switch, weatherproof box with flow from left to right. This control box is...

SPECIAL OPTIONS High temperature: (option HT) requires seals of Viton®, EPR, Kalrez™ or Teflon (compatible with fluid). A thermal barrier (heat-resistant cloth) is added between the housing and the control box, which must be used with service option "W" (weatherproof) or "X" (corrosion resistant). A metal scale is provided. Identification tag: (option ST) customer-supplied information is stamped on a stainless steel tag that is attached to the nameplate. Multi-pin connector: Pin connectors (option PC) are available for rapid field installation. Meters are provided with the male half of...
