Background technology
Electronic water meter flow sensor, for gathering base table, indicator turn signal, thus reaches the object of electronic measurement.Existing electronic water meter overwhelming majority flow sensor is all employing 2 magneto sensors, to prevent the jitter phenomenon that in closed conduct, fluid occurs.But the signal collected is 2 signals, is hard to tell water meter and rotates and reverse.No matter when rotating and reverse, flow sensor is all judged as rotating forward.Because the impact of the water in closed conduct and air causes manifold pressure to change.Cause water meter retrograde rotation sometimes, make base table and electronic watch metering produce error, cause for water both sides dispute.In order to overcome this phenomenon, indivedual producer adopts 3 magneto sensors to be placed on three uniform directions of water meter needle respectively, thisly positive and negative rotation can be identified, but due to water meter limited space, add that sensor bulk is excessive, block the observation of indicator of water gauge, bring inconvenience to user and calibrating department.
The utility model object effectively identifies rotating signal, do not take excessive volume and area again, and user is high-visible to the amount of spin of every bit pointer with calibrating department.
Summary of the invention
The utility model object is to provide a kind of electronic water meter flow sensor that can gather rotating signal, effectively identifies rotating signal, does not take excessive volume and area again, user and evaluation department all high-visible to the amount of spin of every bit pointer.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of electronic water meter flow sensor that can gather rotating signal, this flow sensor is installed on base table, wherein: described flow sensor includes flow sensor and needle, described flow sensor includes magneto sensor, pcb board, magnetic shielding cover and lead-in wire; Magneto sensor is fixedly connected on pcb board, and is positioned within magnetic shielding cover, and is connected with external unit by lead-in wire; Below the watch glass that described needle is arranged on base table counter counter axis on; Vertical corresponding with needle position above the watch glass that described flow sensor is installed on base table, described magneto sensor is fixed on the two ends of pcb board, and described needle rotates forward or backwards, can be induced 4 states of different order by flow sensor.
Effect of the present utility model is:
1, after installing, this device blocks seldom to indicator and scale value, does not affect user's reading and customer demand.
2, the magneto sensor volume adopted is little, lightweight, easy accessibility.
3, owing to adopting the magnetic switch of bipolar latch function and bipolar needle, 4 kinds of signal with different type can be gathered, accurately can judge water meter forward and rotate backward in collection signal metering process.
4, thoroughly overcome needle shake and level bring error in dipping, make electronic counting and base table count Complete Synchronization.
5, effectively prevent external magnetic field from attacking owing to installing magnetic shielding cover additional.
