Flowmeter having a temper proof housing mounted on a pipe section thereof for a telemetering unit including a battery and a circuit

A system for monitoring the flow of water through a pipe comprising

• a pipe section adapted to be located in a water supply line including
• a metering device for presenting readable information representative of the rate of flow through the pipe section,
• a telemetering unit including
• circuit means for reading the readable information presented by said metering device, converting the read information into data representative of the flow through the pipe section and transmitting the data to a remote receiver,
• battery means for powering said circuit means, and
• first housing means having a hermetically sealed compartment for housing said telemetering unit,
• means for interconnecting said housing means and said pipe section including key means on said housing means and keyway, means on said pipe section selectively oriented to prevent relative axial and rotational displacement between the interconnected housing means and said pipe section, and
• second housing means,
• locking means for releasably locking said second housing means on said first housing means to prevent relative movement between said first housing means key means and said pipe section keyway means when said first housing means and said pipe section are interconnected to maintain said first housing means interconnected with said pipe section.
