Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] According to attached Figure 1-Figure 16 It can be seen that a reliable fluid meter of the present invention includes a light-sensing circuit board or light-sensing module 1, a peristaltic pump 2, a pump tube 3 connected to the peristaltic pump 2, a metering rack 4, an upper joint 5, and a lower joint 6. The liquid inlet 8 that the fluid enters and the quartz tube 7 that is fixedly arranged in the metering rack, the light emitter 9 and the light receiver 10 that are in contact with the quartz tube 7 are fixed on the metering rack, one end of the upper joint 5 and The top of the quartz tube 7 is connected, the other end of the upper joint 5 is connected with an end of the pump tube 3, one end of the lower joint 6 is connected with the bottom of the quartz tube 7, and the other end of the lower joint 6 is connected with the bottom of the quartz tube 7. The liqui...

Abstract

The invention discloses a firm-type fluid meter, and the meter comprises a light induction circuit board or a light induction module, a peristaltic pump, a pump pipe connected with the peristaltic pump, a metering rack, an upper connector, a lower connector, a liquid inlet for allowing liquid to enter, and a quartz tube which is fixedly disposed in the metering rack. One end of the lower connector is connected with the bottom of the quartz tube, and the other end of the lower connector is connected with the liquid inlet. A light emitter and a light receiver are respectively connected to the light induction circuit board or the light induction module which provides a working current for the light emitter and the light receiver and collects the voltage signal of the light receiver in real time. One side wall of a second projection is provided with an embedded interface which is parallel to an embedded connector, and the other side wall of a first projection and one side wall of the second projection form an access port which is adaptive to the first projection and is used for the stretching of the projection. The meter effectively irons out the defect that a conventional screw joint part in the prior art is not suitable for the fixing of a photoelectric emitter or receiver in the metering rack.

Description

technical field [0001] The invention relates to the technical field of meters, in particular to a reliable fluid meter. Background technique [0002] In the previous peristaltic pump plus fluid detection meter, the voltage of the photoreceiver was 1 volt when there was no fluid in the quartz tube. When there was fluid and the turbidity was low, the voltage of the photoreceiver was 1.5-2V. Usually, 1.3V was set for the photoreceiver to detect The voltage threshold of the fluid. When the photoreceiver detects a voltage greater than the threshold of 1.3V, the meter is determined to detect fluid; but there is fluid and the turbidity is high. The voltage of the photoreceiver will be less than or equal to 1V. At this time, the photoreceiver If the voltage does not reach the threshold, the meter cannot detect the fluid. [0003] In order to solve such problems, a fluid meter is proposed, which includes a light sensing circuit board or a light sensing module, a peristaltic pump, a ...
