Abstract
The primary application of this force meter is measurement of fluid flow. A force on the force sensor push the force sensor away from the original position. The deviation of the force sensor is detected by a proximity sensor. An electronic unit takes the position signal from the proximity sensor as a feedback. The electronic unit generates electric current to an electromagnetic anti-torque means. The electromagnetic anti-torque means generates an anti-torque on force sensor to prevent the force sensor from moving away from the original position. A display unit measures the electric current and calculates velocity and rate of fluid before displays the results.”

10. A force meter for measuring external force comprising:
-
A) A case; B) A force sensor, said force sensor moves away from an original position when an external force is applied to said force sensor; C) A proximity sensor, said proximity sensor measures a position deviation of said force sensor from said original position, said proximity sensor generates a position signal when a position deviation is detected, the larger said position deviation is the stronger said position signal is; D) An electromagnetic means of anti-force, said electromagnetic means of anti-force generates an anti-force to move said force sensor backwards to said original position while receiving an electric current, the stronger said electric current is the stronger said anti-force is; E) An electronic unit, said electronic unit generates said electric current while receiving said position signal, the stronger said position signal is the stronger said electric current is; F) A display unit, said display unit measures value of said electric current, said display unit converts value of said electric current to value of force, or other value related to force before displaying. - View Dependent Claims (11, 12, 13, 14, 15, 16, 18, 19)
