Abstract

A flow meter includes: a measuring portion having rotors and provided on a pair of shafts positioned horizontally; a sensor that measures a pressure and a temperature within a flow path of the measuring portion; a front side panel that supports front side components of the measuring portion; a front cover that covers the front side components of the measuring portion; a main substrate that is installed in the front cover and collects a signal from the sensor; and a counter displaying portion that displays the signal from the sensor outputted from the main substrate. The sensor is assembled in the tip end of a cylindrical sensor case, the sensor case is inserted into the front side panel through an insertion opening formed in the front cover, the sensor is installed within the front cover, and the sensor and the main substrate are connected to each other.

Claims

1. A flow meter comprising:

a measuring portion, which forms a flow path through which a fluid flows, having rotors that rotate in accordance with a flow rate of the fluid, provided on a pair of shafts that are positioned horizontally;

a sensor that measures a pressure and a temperature within the flow path of the measuring portion;

a front side panel that supports front side components of the measuring portion from outside of the measuring portion;

a front cover that covers the front side components of the measuring portion, from outside of the front side panel, and forms a case that encloses electric components;

a main substrate that is installed in the front cover and collects a signal from the sensor;

a counter displaying portion that displays a signal from the sensor, outputted from the main substrate; and

a counter case that is arranged so as to cover the main substrate and provided in the front cover;

wherein;

the sensor is assembled in the tip end of a cylindrical sensor case, the sensor case is inserted into the front side panel through an insertion opening that is formed in the front cover, the sensor is installed within the front cover, and the sensor and the main substrate are connected.

2. The flow meter as set forth in claim 1, wherein:

the sensor case has two grooves, and O-rings are fitted into each of the grooves.
