1. A cartridge for a flow meter, the cartridge comprising:
- a cartridge housing enclosing a cartridge interior, and configured for removable installation in a mainframe of a flow meter;
a fluid inlet configured for conducting fluid from outside the cartridge housing to the cartridge interior;
a chamber disposed in the cartridge interior;
a chamber inlet communicating with the chamber;
a flow sensor disposed in the cartridge interior and configured for measuring fluid flow rate into the chamber; and
a fluid outlet,wherein the cartridge defines a flow path through the fluid inlet, through the chamber inlet, to the chamber, and toward the fluid outlet.

Abstract
A flow meter for measuring a flow rate of a fluid may include a cartridge containing certain components such as a flow sensor. The cartridge is removable from the flow meter such that it may be replaced with a new cartridge, allowing calibration of the flow meter while enabling the flow meter to continue to be operated with another cartridge in the place of the removed cartridge. The flow meter may be configured to direct fluid flow away from selected components of the flow meter.

15. A method for operating a flow meter, the method comprising:
-
installing a cartridge in a mainframe of the flow meter by moving the cartridge into a receptacle of the mainframe, wherein the cartridge comprises a cartridge interior, a chamber in the cartridge interior, a chamber inlet, and a flow sensor; flowing a fluid through the chamber inlet and into the chamber; while flowing the fluid, operating the flow sensor to measure a flow rate of the fluid into the chamber, wherein the flow sensor outputs a measurement signal; and transmitting the measurement signal to an electronic circuit disposed in the mainframe via the first electrical connector and the second electrical connector. - View Dependent Claims (16, 17, 18, 19, 20)
