Description
Technical field
The utility model belongs to instrument field, more specifically to a kind of change circulation area perseverance differential pressure flowmeter
Remote signal transmitting device.
Background technique
Becoming circulation area perseverance differential pressure flowmeter is gone up and down in vertical taper pipe with changes in flow rate with float, it is changed
Between circulation area come the volume flow instrument measured, also known as spinner flowmeter.Become circulation area perseverance differential flow
Be counted as intuitively to flow instruction or measuring accuracy live indicating meter of less demanding, be applicable in it is existing strong, it is cheap each
Industry, which has, widely to be applied.
Summary of the invention
The utility model provides a kind of flow signal of change circulation area perseverance differential pressure flowmeter low in cost, reliable operation
Teletransmission scheme, can be the real-time teletransmission of flow signal.
To achieve the goals above, the utility model is achieved through the following technical solutions: the flowmeter it is remote
Journey signal transmitting apparatus includes flowmeter 1, magnetic float 2, Magnetic Induction bar 3, transmitter 4, controller 5, the flowmeter 1
It is bundled with Magnetic Induction bar 3 outside, transmitter 4 is connected on the Magnetic Induction bar 3, installation is magnetic floating inside flowmeter 1
Son 2, Magnetic Induction bar 3 and magnetic float 2 constitute an Electromagnetic Coupling System, and transmitter 4 is electrically connected with controller 5.
Preferably, the flowmeter 1 is to become circulation area perseverance differential pressure flowmeter 1.
Preferably, the transmitter 4 includes that UR type electric resistance sensor and UB type R/I conversion module form, Magnetic Induction
Bar 3 is connect with UR type electric resistance sensor, and UR type electric resistance sensor is connect with R/I conversion module.
The utility model the utility model has the advantages that
Scheme can realize the teletransmission of flow signal with cheap cost, can be not only used for product design with mature technology,
It can be used for field retrofit, suitable for needing teletransmission flow signal but being not desired to put into the occasion of more cost.
Detailed description of the invention
Fig. 1 is the utility model structure chart；
In figure, 1- flowmeter, 2- magnetic float, 3- Magnetic Induction bar, 4- transmitter, 5- controller.
Specific embodiment
Below in conjunction with the utility model embodiment and attached drawing, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by, it is clear that described embodiment is only the utility model a part of the embodiment, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, all category scope of protection of the utility model.
As shown in Figure 1, the remote signal transmitting device of the flowmeter includes flowmeter 1, magnetic float 2, magnetic sense
Bar 3, transmitter 4, controller 5 are answered, Magnetic Induction bar 3 is bundled with outside the flowmeter 1, connects on the Magnetic Induction bar 3
It is connected to transmitter 4, magnetic float 2 is installed inside flowmeter 1, Magnetic Induction bar 3 and magnetic float 2 constitute a magnetic coupling system
System, transmitter 4 are electrically connected with controller 5.Become circulation area perseverance differential pressure flowmeter 1, magnetic float 2, Magnetic Induction bar 3 and incudes magnetic
The position of property float 2, outputs signal to controller 5 by transmitter 4.
The flowmeter 1 is to become circulation area perseverance differential pressure flowmeter 1.The transmitter 4 is sensed including UR type resistance
Device and UB type R/I conversion module composition, Magnetic Induction bar 3 are connect with UR type electric resistance sensor, and UR type electric resistance sensor and R/I turn
Change the mold block connection.The magnetic float 2(2 when the interior fluid of flowmeter 1(1) increases) it moves up, the resistance value of Magnetic Induction bar 3 subtracts
It is small, increase the output signal of transmitter 4；Magnetic float 2 moves down when fluid reduces in flowmeter 1, Magnetic Induction bar 3
Resistance value increases, and reduces the output signal of transmitter 4.The effect of transmitter 4 is the change that the variation of translated resistance value is electric signal
Change, and makes the requirement of output signal format adaptation controller 5.
Utility model works principle: being the lifting with the magnetic float in flowmeter 1 with liquid level, remote transmission device is by UR type electricity
Sensor and UB type R/I conversion module composition are hindered, the sensor of the transmitter 4 is fixed on the master of flowmeter 1 in the form bundled
On the outside of conduit, it is in the same Electromagnetic Coupling System of liquidometer.When magnetic float 2 is moved up and down with liquid level, corresponding liquid level
The tongue tube of position is attracted by the effect in magnetic field in float, and resistance chain resistance value changes, by conversion module by the electricity of variation
Resistance signal is converted into the output of two-wire system 4~20mADC standard signal, which is convenient to and electronic type III instrument, display instrument
It matches, can also be matched with light beam instruction, digital vision-control alarm, to reach display, control, adjusting and report
Alert purpose.
Finally, it is stated that preferred embodiment above is merely to illustrate the technical solution of utility model, although rather than limiting
The utility model is described in detail by above preferred embodiment, but it should be understood by those skilled in the art that can
To make various changes to it in the form and details, without departing from the protection scope of the utility model.
