a single sealed housing enclosing the transducers and the electronic circuit;
the housing comprising a cup, a lid and a seal;
a locking mechanism that locks the housing in position relative to the flow channel; and
wherein the flow channel has two holes by which the housing is in contact with the media.
2. The ultrasonic consumption meter according to claim 1 , wherein said locking mechanism consists essentially of screws holding the housing and flow channel together.
3. The ultrasonic consumption meter according to claim 1 , wherein said locking mechanism consists of screws holding the housing and flow channel together and protrusions on said cup.
4. The ultrasonic consumption meter according to claim 1 , wherein said locking mechanism is positioned below said lid.
5. The ultrasonic consumption meter according to claim 1 , wherein said locking mechanism extends from a lower part of the housing and connects to an upper part of the flow channel.
6. The ultrasonic consumption meter according to claim 1 , wherein said lid is transparent.
7. The ultrasonic consumption meter according to claim 6 , further comprising a display inside the housing.
8. The ultrasonic consumption meter according to claim 7 , further comprising a front plate inside the housing.
9. The ultrasonic consumption meter according to claim 8 , wherein said display is a part of the electronic circuit.
10. The ultrasonic consumption meter according to claim 1 , further comprising a locking ring that holds said lid and said cup together.
11. The ultrasonic consumption meter according to claim 1 , wherein the lid is not penetrated by electrical wires.
12. The ultrasonic consumption meter according to claim 8 , wherein said cup has a diameter less than 15 cm and larger than 3 cm such that said housing is of sufficient volume to accommodate said transducers, electronic circuit, display and front plate.
13. The ultrasonic consumption meter according to claim 12 , wherein said cup has a height less than 6 cm and larger than 1 cm.
14. The ultrasonic consumption meter according to claim 12 , wherein said cup diameter extends beyond a width of said flow channel.
15. The ultrasonic consumption meter according to claim 1 , further comprising an o-ring that provides a water tight seal for the housing.
16. The ultrasonic consumption meter according to claim 10 , further comprising an o-ring that provides a seal for the housing.
17. An ultrasonic consumption meter comprising:
a flow channel through which flows a media to be measured;
two ultrasonic transducers that emit and receive ultrasound;
an electronic circuit that operates the meter;
a display for displaying values, said display being part of the electronic circuit,
a single sealed housing enclosing the transducers, the electronic circuit, the display, and a front plate and a power supply;
the housing comprising a cup, a transparent lid that is not penetrated by electrical wires, a seal between said lid and said cup, a locking ring that holds said lid and cup together and an o-ring that provides a seal for the housing;
a locking mechanism, comprising screws positioned below said lid, extending from a lower part of the housing and connecting to an upper part of said flow channel, wherein said locking mechanism locks said housing in position relative to the flow channel; and
wherein the flow channel has two holes by which the housing is in contact with the media.
18. An ultrasonic consumption meter comprising:
a flow channel through which flows a media to be measured;
two ultrasonic transducers that emit and receive ultrasound;
an electronic circuit that operates the meter;
a display for displaying values that is part of the electronic circuit,
a single sealed housing enclosing the transducers, the electronic circuit, the display, and a front plate and a power supply;
the housing comprising a cup with protrusions, a transparent lid that is not penetrated by electrical wires, a seal between said lid and said cup, a locking ring that holds said lid and cup together and an o-ring that provides a seal for the housing;
a locking mechanism, consisting essentially of screws and said protrusions on said cup for holding the housing and flow channel together, said locking mechanism being positioned below said lid, extending from a lower part of the housing and connecting to an upper part of said flow channel, wherein said locking mechanism locks said housing in position relative to the flow channel;
wherein the flow channel has two holes by which the housing is in contact with the media; and
wherein said cup has a diameter less than 15 cm and larger than 3 cm and a height less than 6 cm and larger than 1 with sufficient volume to enclose the transducers, the electronic circuit, the display, the front plate and the power source.
