Abstract

A water meter with an emergency shutdown, is a dual purpose water meter, it records the accumulated water consumptions of individual runs as any regular water meter, detects the water leakage or uncontrolled flow, by comparing each single continuous run (non equal batches) with a target quantity stetted, and shut down the water flow if a single continuous run reach that target. It could be adapted to any type of water meter or method of recording, turbine, vertical turbine, positive displacement, multi jet, propeller, magnetic or electronic flow measuring.

Description

Water meter with an emergency shut-down
Technical field
Adding a feature of an emergency shut down to any water meter. Background art All water meter have a mean to measure the amount of liquid passing while it is flowing, stop recording when the flow stops, and re-continue the recording when the flow restarts. The summations of runs form a totalizer. Some water meter has a batch measuring, also it continues recording until re-setted. It's very rare for a water meter to run continuously for a long time. The quantity flowing in a single run depends on the numbers of users the water meter is serving .like apartment, single house, commercial building or a housing compound.
In normal usage ,a single run amount could be double the average of runs or, tripled or even being six fold of the average runs, beyond that, it mean there is a leakage, or unattended outlet keeping the water meter to continue on recording.
In practice, the only way to cut the flow of water is, either at end of specific batch or manually when the leaked water become visible, this will cause a great deal of damages in building & furniture beside the water losses.
The water meter already measures the amount flowing in each single run from its start and added it up to previous registered quantity .if we copied this single run recording and compare it with a max .target allowed, then, if the amount flowing continuously in a single run reach that target, this mean an emergency due to leakage or uncontrolled flow.
If there is an irrigation system in the house, it will be shown as leak. In this case irrigation water should be taken out of an expansion tank to allow the single run mechanism to be re-setted when the tank is full at intervals.
We could link the setted target with a mechanism to shutdown a valve, now we have a mean to detect the leakage or uncontrolled flow in addition to its function as a water meter. Disclosure of the invention
When the water pass through the water meter, it start recording the quantity passing, when the water stops, recording will stop. This applied even for that those water meters which has independent register for batches. This marginal recording in a single contentious run will be added up to the previous old recording as totalizer. If this single runs movement copied and compared with a maximum feasible run. Then we have a mean to detect the leakage or uncontrolled flow of fluid. If we raise the set of register upward and created a new layer in the totalizer, the top register layer function exactly as original regular water meter
Then we copy the movement from any of the first few gears of the recording set, in a new separate set of gears, in the down layer of totalizer. The copied movement goes through a reduction gear train to reduce the final gear rotation to about a half of rotation. The gear train has a movable gear to engage when the flow start, and disengage when the flow stops. The final gear has a self return spring to clear out the rotation each time the water flow stops to restart again from the beginning at each run. At its end, the final gear has a pointer with a small magnet. If the flowing amount in a single run reach the setted targets, the magnet on the pointer of the single run gear reach the shut down point, were it pull another magnet placed on a ratchet in the shut down valve, it force the flow to stops.
The setted target could be changed within small range be relocating the magnet on the limit gear .when larger range needed a new reduction gear will be added to the geartrain of the single run register ■ The shut down valve has a telescopic column. In its short position with a spring under compression, a ratchet hold the inner and outer columns together, the end of the ratchet has a magnet when it is pulled out by the magnet of the single run gear .the ratchet release the inner portion of the valves column, it expand the column which force the valve to shutdown. Industrial applicability The invention is a regular water meter with two additions. The first is to add separate register to the single runs, the second is to pass either input or output of the water meter through a valve merged to the water meter Description of drawing

It copies the quantity passing from each start of flowing and clears the reading automatic when the flow stops. Only when the quantity passed exceed a pre setted target, it stops the flow automatic by closing a valve - As of claims 1 , a water meter with emergency shutdown, is any liquid meter has a shut down of flow only when the quantity passing in single run exceeding a pre setted limit - As of claims 1 , a water meter link with a valve to shut down only when a target quantity is reached in a single continuous flow without interruption as indication
• of emergency. - As of claims 1, a water meter register clears the reading when the flow stops automatically. Only in one special case, when flow runs continuously to reach a setted target, then it signal (mechanical limit / electronic impulse ) to a valve to shut down the flow . - As of claims 1, a water meter has valve with an expandable column, it will be expanded, when it receives a signal from the sub register to close the valve as emergency. - As of claims 1 , any mean to estimate a continuous single run quantity of liquid to compare with average regular consumption as indication of emergency.
