Abstract
The utility model discloses a flow meter signaling device which belongs to a metering device for liquid flow quantity or gas flow quantity, particularly metering device part applying the electromagnetic effect. The flow meter signaling device comprises a meter body, an indicating needle, a fixing ring and a sensor installing pipe. The flow meter signaling device has the structure that both sides of a rotating shaft are symmetrically provided with permanent magnets with opposite polarities, and a wiegand sensor is arranged in a sensor installing pipe. The structure of the utility model is simple, the manufacture can be carried out by the slight change of an original production line; the reliability and the weatherability are high. The utility model which can be used for intelligent meters as well as can be used for remote transmission is suitable for being used in various flow meters adopting indicating needles or number wheels to carry out indication.
Description
Affiliated technical field
The utility model belongs to liquid or gas flow measurement apparatus, particularly uses the measuring equipment part of galvanomagnetic effect.
Background technology
Flow instrument is represented one of the most frequently used measuring instrument, in order to realize that electricity shows or a large amount of now signal transmitters that use of long-range display machines control are that magnet is installed on pointer, the set collar that has the sensor mounting pipe is installed above surface plate, the tongue tube sensor is housed in the mounting pipe, the magnet that is installed on the pointer is realized switch motion with pointer rotary inductive tongue tube, thereby the rotation of pointer is converted to electric signal to be spread out of, this technical scheme is simple in structure, easy to use, but there are some shortcomings, as: be subject to the influence of pipeline water hammer, cause mistaking signal; Interior the freezing of the back water meter of enduring cold causes tongue tube to damage; Easy magnetization affected by magnetic fields and performance failure.
Summary of the invention
The purpose of this utility model provides a kind of reliable technical scheme that is not subjected to the novel flow instrument signal transmitter of climate change and influence of magnetic field.
The technical solution of the utility model is, the flow instrument signal transmitter comprises, table body, pointer, set collar, sensor mounting pipe, and its structure is: the rotating shaft of pointer is monosymmetric is equipped with opposite polarity permanent magnet, and Wei root sensor is housed in the sensor mounting pipe.
Described pointer is gear type or pointer-type or character wheel formula.
Principle of work of the present utility model be rotate all permanent magnets when pointer reversing once, Wei root sensor spreads out of a pulse signal, for processor adopting.This sensor can or not damage because of humidity in the water meter because of the influence generation misoperation of external magnetic field variation, thereby has improved the reliability and the weatherability of signal transmitter.The utility model is simple in structure, can change a little on original production line and just can make production, and reliability and weatherability height both can be used for intelligence instrument, can be used for remote transmission again, is applicable to that the flow instrument that all kinds of employing pointers or character wheel are done to indicate adopts.
