Abstract

The utility model provides an electronic flowmeter used for collecting, displaying and transmitting liquid flow signals. The flowmeter is especially used in the processes of the water conservancy and the hydroelectricity exploration and for displaying the instantaneous water discharge and transmitting the signals during a hole-drilling water test. The utility model using a liquid crystal display has the advantages of electricity saving, exact and reliable counting, simple and reasonable structure, etc. The power consumption of the whole machine not exceeds 2 mA, and the electronic flowmeter is especially adapted to the work under strong light in field. In addition, the display is clearer if the light ray is stronger.

Description

Liquid crystal display electronic flowmeter

The utility model relates to the electronic flow-meter that a kind of collection that is used for fluid flow rate signal shows and transmits, and this flowmeter is especially in water conservancy, the water power exploration process, and the demonstration of instantaneous discharge and signal transmit when doing water pressure test in borehole.

China is when packer permeability test at present, used flowmeter is actually the water meter of expression accumulated water volume, this water meter has only with time meter unites use, and just can draw flow value by calculating, promptly can't reflect intuitively with this water meter and the transient change of flow mistake take place easily again, simultaneously the flow signal that obtains can not be sent to the upper level intelligence instrument and carry out subsequent treatment, the personnel that construct in the open air and operate ceaselessly see the table timing, see water meter, and labour intensity is very big.

The purpose of this utility model is exactly to provide a kind of brand-new flow to show meter, and it can directly show the flow value in the packer permeability test process, gathers the signal that comes simultaneously and can also send the analyzing and processing that upper intelligence instrument is done further data to.

The purpose of this utility model is achieved in that this flowmeter is the collecting part by flow signal, and stube cable, flow monitor instrument three parts are formed, and the collecting part of its flow signal is by common water meter, the infrared signal sensor, and the signal accessory power outlet is formed; The two ends of stube cable have plug respectively; Flow monitor instrument is made up of watchcase, battery case, upper end cover, the circuit board that has electronic component, power switch, bottom end cover, input jack, output plughole and LCD.Its infrared photoelectric sensor is installed on the water meter, battery case and upper end cover are glued together, output plughole and input jack and bottom end cover are linked together, switch is installed in wiring board one end, LCD is installed in the wiring board other end, wiring board is put into the machine box, input plug is inserted on the input jack, in water meter, there are current out-of-date, infrared sensor is with the signal process accessory power outlet of picking up, cable, input plug, the 1st pin that input jack is delivered to IC7 carries out shaping, amplify, signal after the amplification on the one hand by IC7 the 4th pin deliver to output plughole as with the interface signal of upper instrument, deliver to by IC4 by IC11 on the other hand, IC5, the counting circuit that IC6 forms is counted, then by IC9, the timing circuit that IC10 forms provides a latch signal when the time reaches setting value, the count value of storing in the counting circuit is sent into by IC1, IC2, in the decoder driver circuit that IC3 forms, drive liquid crystal display displays outflow value.

The utility model is owing to adopt LCD, very power saving, and the complete machine power consumption is no more than 2mA, also is fit to very much the work down of open-air high light simultaneously, and light is stronger, and it is more clear to show, and the while, it also had counting accurately and reliably, advantage such as simple and reasonable.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1, be liquid crystal display electron flowmeter perspective view;

Fig. 2, be liquid crystal display electron flowmeter electronics schematic diagram.

Describe concrete structure of the present utility model and operating position in detail below in conjunction with accompanying drawing: this flowmeter is the collecting part by flow signal, stube cable, flow monitor instrument three parts are formed, the collecting part of its flow signal is by common water meter 4, infrared signal sensor 3, signal accessory power outlet 2 is formed; The two ends of stube cable 1 have plug 14 and accessory power outlet 2 respectively; Flow monitor instrument is made up of watchcase 5, battery case 6, upper end cover 7, circuit board 9, power switch 10, bottom end cover 11, input jack 12, output plughole 13 and LCD 8.Its infrared photoelectric sensor 3 is installed on the water meter 4, battery case 6 is glued together with upper end cover 7, output plughole 13 and input jack 12 are linked together with bottom end cover 11, switch 10 is installed in an end of wiring board 9, LCD 8 is installed in the other end of wiring board 9, wiring board 9 is put into machine box 5, and input plug 14 is inserted on the input jack 12.In water meter 4, there are current out-of-date, infrared sensor 3 is with the signal process accessory power outlet of picking up 2, cable 1, input plug 14, the 1st pin that input jack 12 is delivered to IC7 carries out shaping, amplify, signal after the amplification on the one hand by IC7 the 4th pin deliver to output plughole as with the interface signal of upper instrument, deliver to by IC4 by IC11 on the other hand, IC5, the counting circuit that IC6 forms is counted, then by IC9, the timing circuit that IC10 forms provides a latch signal when the time reaches setting value, the count value of storing in the counting circuit is sent into by IC1, IC2, in the decoder driver circuit that IC3 forms, drive LCD 8 and demonstrate flow value.
