New Electronic Propeller Meter

7/1/98 -- Announcing the FM104 MainLine(tm) electronic propeller meter. This new electronic propeller meter features fewer moving parts and a rugged Sparling design for longer life and reduced maintenance costs.

The Model 104's battery powered electronic rate/totalizer, senses the propeller rotation via a magnetic pickup sensor located in the gearbox and translates these pulses to rate and total flow. The electronics are completely isolated from the flow stream in a NEMA-4X enclosure. A photoelectric cell activates the display when the cover is opened. The display goes into "sleep mode" when the cover is closed. The lithium battery is rated for 8 years.

All meter parameters are held in non-volatile EEPROM memory. Full scale, span, K, engineering units, dampening parameters can all be modified to suit your changing needs in the field with an optional programming unit.

The Model 104 is available with optional 4-20 mA and pulse output when the totalizer is connected to an outside power source and is available with integral or remote totalization at a distance of up to 50 feet. Available in sizes from 2" to 14", accuracy ± 2%.
