- the analysis means may be programmed to display and / or blocked counter information when the difference of temperature ( ⁇ ) is greater than a predefined threshold, for example 5 ° C, and the flow rate value provided by the meter is zero.
- the fluid temperature sensor may be installed downstream or upstream of the meter, in the vicinity of this meter or directly be integrated in the meter.
- the analysis means can be programmed to periodically perform analyzes and to emit a blocked counter information only after a minimum number of analyzes, over a given period, indicating a temperature difference ( ⁇ ) greater than a limit. determined while the flow rate value provided by the counter is zero.
- the analysis means are programmed to perform an accumulation of the time during which the temperature difference ( ⁇ ) exceeds the limit determined while no flow is indicated by the meter, and to emit a counter information blocked only when the cumulative time exceeds a predetermined value.
- the counter includes a display on which an indication of the "counter blocked" type is displayed when the blocking is detected.
- the electronic equipment is preferably provided for transmitting the counter information blocked remotely.
- the invention more specifically relates to a water meter having the characteristics defined above.
- Fig. 1 is a diagram of a device for detecting the blocking of a mechanical fluid meter according to the invention.
- Fig. 2 is a schematic elevational view of a mechanical fluid meter incorporating a blocking detection device according to the invention.
- Fig. 3 is a graphical representation, as a function of the time plotted on the abscissa, of a variation of flow carried on the ordinate on the left axis of ordinates and of the variation of the temperature difference between fluid and ambient temperature carried on the axis of ordered right, and
- Fig. 4 is a representation of a decision grid for blocking detection.
- a device D for detecting the blocking of a mechanical meter 1 of fluid more particularly a water meter, installed on a pipe 2.
- the meter 1 comprises an upstream connection 1a and a downstream connection 1b the fluid flowing in the direction of the arrows F from left to right according to FIG. 1.
- the outputs of the sensors 3, 4 are respectively connected to an input of an electronic assembly E comprising analysis means 5 for determining the difference of the temperatures provided by the sensors 3 and 4 and for carrying out a generally periodic analysis of this difference taking into account the value of the flow of fluid supplied by the counter 1.
- This value is generally supplied to the set E by a transducer 6 installed on the meter.
- the detection device D may constitute a separate unit that will be installed on a mechanical meter not yet equipped with an electronic part.
- the electronic assembly E is already installed on the counter 1, with the transducer 6 as illustrated in FIG. 2.
- the meter is generally equipped with a radio transmitter 7 with antenna 8 for remotely transmitting the information of the measured flow rate.
- the electronic assembly E is adapted, in particular by programming, to ensure the function of the analysis means 5.
- the fluid temperature sensor 3 can be installed on the downstream connection 1b.
- the output of the sensor 3 is connected by a conductive wire 3a to the electronic assembly E.
- the ambient temperature sensor 4 can be installed above the casing of the transmitter 7 and be connected by a non-visible conductive wire to set E.
- the output of the equipment E is connected to the transmitter 7 so that the blocked counter information can be transmitted by radio, by the antenna 8.
- the fluid temperature sensor could be installed on the upstream fitting 1a, or in the meter body itself.
- fluid temperature sensors for example an upstream sensor and a downstream sensor could be provided, as well as several ambient temperature sensors to obtain a representative average.
- the meter With two temperature sensors 3, 4 one for measuring the temperature of the fluid, the other the ambient temperature and connect these sensors to the electronic assembly E comprising a computer which will be programmed to constitute the analysis means 5 and estimate the temperature difference ⁇ between the fluid and the ambient temperature.
- the electronic assembly E comprising a computer which will be programmed to constitute the analysis means 5 and estimate the temperature difference ⁇ between the fluid and the ambient temperature.
- the principle of detection is based on the fact that the water distributed to the final consumer is conveyed by a buried distribution network, usually about 1 m below ground level to be protected from frost.
- the temperature of the water is therefore close to 15 ° C.
- the ambient temperature is different from the temperature of the water dispensed: in summer, for a meter installed in a look or in a single house, the ambient temperature may well exceed 20 ° C. It is therefore common to note, depending on the season, significant temperature differences (several degrees) between water and the ambient when the water circulates for a long enough time in the meter.
- the counter 1 If the counter 1 is blocked, i.e. if it does not provide any measured flow value even though liquid is flowing through the meter, the Flow measurement provided by the meter will systematically be zero, even in the case of a large actual flow. In this case, a significant ⁇ value will therefore be obtained for a prolonged measured zero flow rate, which is an abnormal situation: it can then be concluded, at this point, unequivocally, that the counter 1 is blocked.
- Fig. 3 illustrates the variation of the temperature difference ⁇ represented by the curve A in dashed lines, the values of ⁇ expressed in ° C being plotted on the ordinate axis situated on the right of the figure.
- the time is plotted on the abscissa and expressed in seconds.
- the actual flow is represented by curve B in full line and flow values are plotted on the y-axis on the left and expressed in liters / hour or L / h.
- the flow rate is zero until about 20 s. Consequently, the value ⁇ (difference between the ambient temperature and the fluid temperature) is zero. At the moment 20 s, the flow rate increases sharply to the value of 500 L / h. The temperature difference ⁇ increases, with a certain delay, to reach the value of 4 ° C. When the flow is cut to the instant 100 s and remains cut, the value of ⁇ goes down to the zero value reached at the instant 170 s.
- This decrease in the difference ⁇ when it is detected and no flow is indicated by the counter, constitutes an alert indicating that the counter is blocked or faulty.
- the operation is similar, but the values are reversed: the fluid temperature is higher than the ambient temperature in case of actual flow.
- ⁇ is the difference between the fluid temperature and the ambient temperature. But the principle of blocking detection of the counter remains the same: if ⁇ is important, and if the measured flow rate provided by the counter is zero, it is deduced that the counter is blocked.
- Fig. 4 summarizes the decision grid for the detection of the blocking and illustrates the blocking detection algorithm introduced into the analysis means 5 of the electronic assembly E.
- Line L1 corresponds to a low temperature difference ⁇ , for example less than 1 ° C. whereas line L2 corresponds to a significant ⁇ , for example example above 5 ° C.
- Column C1 corresponds to a flow rate measured by the counter of zero value while column C2 corresponds to a non-zero flow, for example greater than 10 L / h.
- Boxes L1 C1 and L2C2 correspond to a normal operation that does not trigger an alarm.
- Box L2C1 corresponds to abnormal operation and produces a blocked counter alert.
- Box L1 C2 corresponds to an indeterminate case that does not trigger an alert.
- the small difference in temperature when the flow rate is not zero results from a small difference between the ambient temperature and the fluid temperature.
- the blocking detection algorithm will take into account the fact that the phenomena of temperature variation are slow and that it will be necessary to wait stabilization periods for the measurements to be really usable.
- Certain periods of the year will be more conducive to the effective detection of blocked meters, particularly the extreme temperature seasons (summer, winter) that can generate significant temperature differences between the fluid and the ambient temperature.
- the alarm "counter blocked” can be reported on the meter 1 display.
- an alarm can be transmitted by the antenna 8 to warn the operator immediately after the appearance of the fault, which will quickly trigger a change of meter, reducing by consequently, the quantity of water distributed without associated billing.
