1 PDF Published May, 04 Variable Area Flow Meters Chemline F Series Variable Area Flow Meters are ideal for plastic piping. They provide a combination of accurate visual flow rate measurement and clear flow indication from a distance. Optional limit switches allow the units to signal a low or high flow alarm. An optional flow transmitter provides a 4 to 0 ma signal output. These flow meters must be installed vertically with flow upward.

For liquids with densities and viscosities similar to water (ie. specific gravity of.0 and viscosities between 0.5 cp and. cp) the standard water scale will be accurate enough. The table below shows correction factors to be applied for liquids with specific gravities other then.0. Multiply the correction factor by the water scale value to obtain actual flow rate. Example: For a liquid of specific gravity of.66, the correction factor is For water flow range of 00 to 000 litres/hr, corrected range becomes 74 to 740 litres/hr. Viscosity should be between 0.5 cp and. cp for standard scales to be accurate. For sizing liquid flows ie. determining actual flow range of a tube, please advise the chemical name, concentration, temperature, specific gravity and viscosity. Custom direct reading scales in any units are available special order. SCALE CORRECTION FACTORS FOR LIQUIDS WITH SPECIFIC GRAVITIES OTHER THAN.00 Specific Gravity Scale Correction Factor

5 LSFLO Reed Limit Switch for FC & FS flow meters The LSFLO limit switches serve as switches for minimum or maximum flow values. The normally open latching reed switch closes when the float in the measuring tube reaches and exceedes the switching position. The switch condition is maintained as long as the float is above the limit switch and will open when the float in the tube drops below the switch. Normally closed switches are available on request. technical Operating voltage: maximum 0 VAC Operating current: maximum 0.5 A Constant current when switched: maximum A Rupturing capacity: maximum 0 W/0 VA Closed resistance: < 50 mω Open resistance: > 0 0 Ω Operating temperature: 0oC(oF) to 55oC(oF) CONNECTIONS Protection: IP 65 (DIN EN 6058) Hysteresis (switch on and off point): mm Protection: IP 65 (DIN EN 6058) Dimensions: 4 x 7 x 4 mm Weight (with plug): 40 g Connections: the polarity of the connections has no influence on the function INSTALLATION Screw clamps are used to fit the LSFLO on the dovetail guide of the flow meter. ASV START-UP Prior to the first start up it is important that the float passes the LSFLO switch three times to ensure the electronics inside recognize the magnetic field from the floats properly. 55 Guardsman Road, Thornhill, ON, LT 6L, Canada ISO 900:008 Certified
