Abstract
The invention discloses a novel flow sensor module. The novel flow sensor module comprises a bush, a casing pipe, an upper collet, a lower collet, a rotating shaft, shaft tips, a magnet and a Hall device, wherein magnetic cores are arranged on the rotating shaft, and are arranged between the upper collet and the lower collet through the left and right shaft tips to form a rotor which rotates freely, and the upper collet and the lower collet are arranged on a support; a plurality of magneto sensors are arranged a groove of the support, and a signal of a flow sensor is sent by one magnetic core and is received by the plurality of magneto sensors; and the magnet is arranged on an impeller assembly and is matched with the positions of the magnetic cores. The novel flow sensor module has the advantages that: (1) the economic benefit is remarkable, an original photoelectric sensor assembly is sold at a unit price of about ten thousand yuan, but the cost of the Hall device type sensor module is lower than one thousand yuan; and (2) the sensor has a simple and reliable structure, is difficult to damage and has steady performance.
Description
Technical field
The present invention relates to be used for the sensor of oil field kinetic measurement down-hole liquid continuous flow, mainly is a kind of novel flow sensor assembly.
Background technology
The continuous flow instrument plays a part very important in the detection of dynamic process of oilfield as a kind of instrument of measuring fluid flow in oil field.At present, the continuous flow instrument adopts the photoelectricity assembly as its sensor cluster, but the photoelectricity assembly is an outsourcing piece, overall price costliness (unit price is about 10,000), and sensitivity is not high, fragile.
Summary of the invention
Purpose of the present invention will overcome the deficiency of above-mentioned technology just, and provides a kind of simple in structure, dependable performance and low-cost novel flow sensor assembly.
The present invention realizes the technical scheme that purpose adopts.This novel flow sensor assembly, comprise by lining, sleeve pipe, go up collet, lowerside stone seat, axis of rotation, pivot, magnet and hall device, magnetic core is contained on the axis of rotation, and by about two pivots be installed between collet and the lowerside stone seat, the rotor that formation rotates freely, last collet and lowerside stone seat are rack-mount; A plurality of magneto sensors are installed in the groove of support, and the signal of flow transmitter is sent by a magnetic core and received by a plurality of magneto sensors; Magnet is arranged on the impeller assembly, is complementary with the position of magnetic core.
As preferably, described magneto sensor has four.
As preferably, magnetic core, pivot, axis of rotation, go up the bottom that collet, lowerside stone seat and support are installed in sleeve pipe, cover by lining.
The effect that the present invention is useful is: 1. economic benefit is obvious, and former photoelectricity assembly sensor unit price is about 10,000 yuan, and Hall device formula sensory package cost is less than 1,000 yuan; 2. sensor construction is simple and reliable, not fragile and stable performance.

The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
Novel flow instrument sensor cluster of the present invention mainly is made up of lining 1, sleeve pipe 2, last collet 6, lowerside stone seat 7, axis of rotation 5, pivot 4, magnet and hall device, as shown in Figure 1.Magnetic core 3 is contained on the axis of rotation 5, and by about two pivots 4 be installed between collet 6 and the lowerside stone seat 7, the rotor that formation can rotate freely flexibly, collet is installed on the support 8 up and down; Magneto sensor 9 has four, is installed in the groove of support 8, and the signal of flow transmitter is sent by a synchronous magnetic core and received by a plurality of magneto sensors, not only can receive the external signal speed, can also judge the flow direction of flow.All above-mentioned parts all are installed in the bottom of sleeve pipe 2, cover by lining 1, and are not fragile to protect them.In the instrument well logging process, downhole fluid impeller assembly 11 rotates, thereby the magnet on the impeller assembly 11 10 rotates, and the magnetic core 3 of sensor cluster is experienced the variation of external magnetic flux, rotates thereby produce pull(ing) effect.When axis of rotation 5 drive magnet revolutions moving enclose, each magneto sensor 9 can be sensed the variation of magnetic flux, thereby respectively export a pulse signal, signal processing circuit is carried out pulsewidth adjustment, signal shaping, the judgement of multiple signals phase place to each the road pulse signal that receives, thus the rotating of output flow pulse signal and flow sign.
Novel flow instrument sensor cluster of the present invention adopts magnetic core and a plurality of magneto sensor as flow transmitter, can substitute former photoelectricity assembly sensor fully, realize the measurement of flow size and direction, the volume of this sensor is little, stability is high, cost is very low, can reduce the cost of continuous flow instrument greatly.
In addition to the implementation, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
