Problems solved by technology

Such readings must be precise, the transmission of consumption readings need only be done periodically
[0003] Even when measurements need only be taken and reported periodically, the sensor used to sense and measure fluid flow consumption may require constant power and is often a relatively expensive part of the flow meter
Such sensors additionally consume power and do not take advantage of standby periods during which measurements are not required to be taken and transmitted

Embodiment Construction

[0010] For illustrative purposes, as shown in the figures, new techniques are disclosed herein for flow meters and methods of flow measurement of fluids to be measured, such as gas and water. In a flow meter capable of measuring and delivering such fluid flow, a sensor element receives a flow input of the fluid to be measured and outputs a flow output of the fluid to be measured; a battery element powers the flow meter. The sensor element has an inductance element and a magnetic element connected to the inductance element. The inductance value of the inductive element of the sensor changes in response to movement of the magnetic element relative to the inductive element caused by a fluid pressure differential of the fluid being measured.

[0011] As shown with respect to certain embodiments, the flow meter further includes: a reference clock element connected to the sensor element; a clock element connected to the inductive element; a controller element connected to the refere...

Abstract

A flow meter for measurement of a metered fluid has a sensor element that receives a flow input of a metered fluid and outputs a flow output of the metered fluid, and a battery element. The sensor element has an inductor element and a magnetic element coupled to the inductor element. In response to movement of the magnetic element relative to the inductor element caused by a fluid pressure differential of the metered fluid, the inductive value of the inductor element changes.

Description

technical field [0001] The present invention relates to flow meters. Background technique [0002] Flow meters are used to measure the consumption of a fluid flow to be measured, such as gas and water to be measured. So-called "smart meters" are additionally able to periodically transmit readings of fluid consumption to a network of data readers. Such readings must be precise, the transmission of consumption readings need only be done periodically. [0003] Sensors used to sense and measure fluid flow consumption may require continuous power, and are often a relatively expensive part of a flow meter, even when only measurements need to be taken and reported periodically. Such sensors additionally consume power and do not utilize standby periods during which measurements need not be taken and transmitted. Contents of the invention [0004] One embodiment of the present invention provides a flow meter comprising: a sensor element receiving a flow input of a fluid to be me...
