Claim 3

A flow meter as claimed in Claim 1, further including calibration means connected to the electric counter means for calibrating fluids of different viscosities.

Claim 4

A flow meter as described in Claim 1 further including fluid volume reset means connected to the electric counter means (18) for resetting the count displayed on the face of the housing (12).

Claim 5

A flow meter as claimed in any of claims 1 to 3, wherein the shaft supports (46) include fluid ports (56) therethrough for receiving the fluid therein and in and around the turbine shaft (40).

Claim 6

A fluid meter as claimed in any preceding claim, wherein the shaft supports include a support base (44) and a plurality of support arms (48) extending outwardly therefrom, the ends of the arms (48) attached to the sides of the fluid opening (26).

Claim 7

A lightweight battery operated flow meter for mounting in a fluid delivery line for dispensing fluids of various viscosities and reading the amount of fluid dispensed, the flow meter being characterised in that it comprises: a meter housing (12) having a display cavity (24) disposed in the top thereof and a fluid opening (26) therethrough, the opposite ends (28,30) of the housing (12) adjacent the opening (26) are threaded for coupling to the delivery line; a turbine (32) having a turbine rotor (34) with a turbine shaft (40) extending outwardly from the opposite ends of the rotor (34), the turbine further having a plurality of turbine blades (36) extending outwardly from the sides of the turbine rotor (34), each blade (36) having a ferrous slug (38) embedded in the end thereof; a pair of shaft supports, the shaft supports (46) including a support base (44) with a plurality of support arms (48) extending outwardly therefrom, the ends of the support arms (48) attached to the sides of the opening (26), the support base (44) receiving the turbine shaft (40) therein; a pickup coil (50) provided with magnet (52) mounted in the display cavity (24) of the housing (12), the magnet (52) being disposed adjacent the outer periphery of the opening (26) for sensing and counting magnetic pulses as the turbine blades (36) with the ferrous slugs (38) are rotated thereby; and electric counter means (18) for converting the magnetic pulses to a readable count, the readable count being displayed on a digital counter mounted in the top of the display cavity (24) of the housing (12).

Claim 8

A lightweight battery operated flow meter for mounting in a fluid delivery line for dispensing fluids of various viscosities and reading the amount of fluid dispensed, the flow meter being characterised in that it comprises: a meter housing (12) having a display cavity (24) disposed in the top thereof and a fluid opening (26) therethrough, the opposite ends (28,30) of the housing (12) adjacent the opening (26) are threaded for coupling to the delivery line; a turbine (32) having a turbine rotor (34) with a turbine shaft (40) extending outwardly from the opposite ends of the rotor (34), the turbine further having a plurality of turbine blades (36) extending outwardly from the sides of the turbine rotor (34), each blade (36) having a ferrous slug (38) embedded in the end thereof; a pair of shaft supports, the shaft supports (46) including a support base (44) with a plurality of support arms (48) extending outwardly therefrom, the ends of the support arms (48) attached to the sides of the opening (26), the support base (44) receiving the turbine shaft (40) therein; a pickup coil (50) provided with magnet (52) mounted in the display cavity (24) of the housing (12), the magnet (52) being disposed adjacent the outer periphery of the opening (26) for sensing and counting magnetic pulses as the turbine blades (36) with the ferrous slugs (38) are rotated thereby; and electric counter means (18) for converting the magnetic pulses to a readable count, the readable count being displayed on a digital counter mounted in the top of the display cavity (24) of the housing (12).

Claim 9

A flow meter as claimed in Claim 6, further including calibration means connected to the electric counter means for calibrating fluids of different viscosities prior to dispensing fluid through the delivery line.

Claim 10
