A fluid measurement device and methods of manufacturing and using the same are disclosed. The fluid measurement device includes a conduit configured to transport a fluid, a conductivity sensor in the conduit, and a voltage sensor in the conduit and having first and second rings, probes, or plates. The conductivity sensor is configured to determine the conductivity of the fluid. The voltage sensor is configured to receive a first voltage on the first ring, probe, or plate and detect a capacitance or a second voltage on the second ring, probe, or plate. A value of the capacitance or second voltage corresponds to the amount of fluid in the voltage sensor. The total amount of fluid through the conduit may be determined from amount of fluid in the voltage sensor, the fluid flow rate, the fluid velocity, and the number of samples or the sampling rate.

1. A fluid measurement device, comprising: a) a conduit configured to transport a fluid;b) a conductivity sensor in the conduit, configured to determine (i) a conductivity of the fluid or (ii) a first voltage or a first capacitance across at least part of the fluid;c) a voltage sensor in the conduit
1. A fluid measurement device, comprising: a) a conduit configured to transport a fluid;b) a conductivity sensor in the conduit, configured to determine (i) a conductivity of the fluid or (ii) a first voltage or a first capacitance across at least part of the fluid;c) a voltage sensor in the conduit and having first and second rings, probes, or plates, the voltage sensor being configured to (i) receive a predetermined voltage on the first ring, probe, or plate and (ii) detect a second capacitance or a second voltage on the second ring, probe, or plate, wherein a numerical value of the second capacitance or the second voltage corresponds to an amount of the fluid in the conduit between the first and second rings, probes, or plates; andd) a processor configured to: (1) determine the conductivity of the fluid from the first voltage or the first capacitance across the part of the fluid when the conductivity sensor determines the first voltage or the first capacitance across the part of the fluid and(2) measure or calculate a volume of the fluid from: (i) the determined conductivity of the fluid,(ii) the second capacitance or the second voltage,(iii) a predetermined angle of the conduit, and(iv) a distance that the fluid travels prior to entering the fluid measurement device, from an initial reference point to the conduit. 2. The device of claim 1, wherein the conduit comprises a cylinder or a tube. 3. The device of claim 2, wherein the cylinder or tube comprises a non-conductive material. 4. The device of claim 3, wherein the non-conductive material comprises a plastic, glass, ceramic, porcelain, rubber, fiberglass, and/or a combination thereof. 5. The device of claim 1, wherein the voltage sensor extends from an uppermost surface of the conduit to a lowermost surface of the conduit. 6. The device of claim 1, wherein the first and second rings, probes, or plates of the voltage sensor are spaced apart from each other at a first predetermined distance. 7. The device of claim 1, wherein the conductivity sensor is on or along the lowermost internal surface of the conduit. 8. The device of claim 7, wherein the conductivity sensor comprises first and second electrodes spaced apart from each other by a second predetermined distance. 9. The device of claim 1, further comprising a memory including a look-up table having plurality of columns and a plurality of rows, the look-up table storing values of a volume of the fluid in the voltage sensor corresponding to a particular combination of the conductivity of the fluid and the value of the capacitance or the second voltage. 10. The device of claim 1, wherein the processor is further configured to determine the amount of the fluid from a velocity of the fluid, the velocity of the fluid being based on or determined from an angle of the conduit. 11. The device of claim 1, wherein the processor is configured to calculate a weight and/or volume of the fluid by: a) calculating a flow rate of the fluid from the amount of the fluid in the conduit between the first and second rings, probes, or plates and a velocity of the fluid;b) dividing the flow rate of the fluid by a number of samples or measurements of the amount of the fluid in the conduit between the first and second rings, probes, or plates per unit time to determine a plurality of quotients; andc) accumulating the quotients until the fluid stops flowing through the conduit. 12. The device of claim 11, wherein the processor is further configured to adjust the weight and/or volume of the fluid based on a variation of a temperature of the fluid from a reference temperature. 13. A milking system, comprising: a) the fluid measurement device of claim 1;b) a milking claw; andc) a hose through which the fluid travels prior to entering the fluid measurement device, wherein the hose connects the milking claw to the fluid measurement device. 14. The system of claim 13, further comprising a user interface device configured to provide a command to start and/or stop a process for measuring the fluid. 15. The device of claim 1, wherein the initial reference point is in a hose to which the conduit is connected and through which the fluid travels prior to entering the fluid measurement device or at an end of a milking claw to which the hose is connected.
