Embodiment approach 1

[0054] Embodiment 1: A trough-type flow detection smart sensor designed for a coking plant. The Parshall tank is designed according to the basic law of the Bernoulli principle of open channel fluid mechanics, and the flow tank with the maximum flow rate of 250L / S is designed, and the fluid level in the tank changes between 0.03m and 0.60m. The sink is made of glass fiber reinforced plastic. The tank body is composed of three parts: a uniformly contracted section 9 with a horizontal bottom surface in the upstream of the throat, a throat section 13 with a descending slope bottom surface and a narrow side width and parallel to each other, and a downstream uniform diffusion section 10 with a rising slope bottom surface. Composition; a dovetail groove 14 is opened at two-thirds of the contraction section from the Houdao section, so that the plate-type smart sensor 11 is embedded in the groove. The plate-type smart sensor 11 is divided into two parts, one is the signal detection part ...

Embodiment approach 2

[0055] Embodiment 2: A trough-type flow detection intelligent sensor designed for a sewage plant. Design a flow tank with a maximum flow of 4000L / S, and the fluid level in the tank changes between 0.08m and 0.80m. The sink is made of glass fiber unsaturated polyester composite material, the sensor structure shell is made of plastic insulating material, and finally the circuit chip part and the internal circuit and structure shell are cast into a plate sensor with a plastic waterproof insulating material. The front of the plate Installed with 100 MFC7710B detection chips, 1 MFC7720B signal processing chip, 1 nRF401 wireless transmission circuit board and 1 power supply circuit board. 800 sampling sensing points are fixed on the back of the chip, and the others are the same as in Embodiment 1.

Embodiment approach 3

[0056] Embodiment 3: A trough-type flow detection smart sensor designed for irrigation areas. Design a flow tank with a maximum flow of 93040L / S, and the fluid level in the tank varies between 0.09m and 1.83m. The water trough is designed in accordance with the basic laws of Bernoulli principle of open channel fluid mechanics, and it is built with cement. The plate-type smart sensor is built on the measuring wall of the contraction section of the sink. The internal chip skeleton of the sensor is made of epoxy resin board. 240 MFC7710B detection chips, 1 MFC7720B signal processing chip, 1 nRF401 wireless transmission circuit board and 1 power supply circuit board are installed on the front of the board. There are 1900 sampling sensing points fixed on the back of the chip. The longitudinal resolution of the sensing point detection is 1mm, made of nickel-chromium alloy. During installation, the center line of the water tank coincides with the center line of the channel, so tha...

Abstract

The invention relates to a sensor and preparation for sewage flux detection. It is used for the water flux auto-detection, control and management in the city environment protection, mine, metallurgy, constructing material, electric power and chemical industry. The device is made up of the open-channel flux slot and the board intelligent sensor. The open-channel flux slot is designed according to the open-channel hydrodynamics Bernoulli's theory. The board intelligent sensor is divided into two parts: one part is signal detection part; the other is intelligent data processing part and the wireless data transforming part. The detection signal is not been influence by the temperature and pressure. The detection error is small and stable, reliable. It is not adhered by the mud and sewage. It is convenience to be installed, used and maintained. It is proper for the flux meter of the wild open-channel and the cloacae out.

Description

1. Technical Field [0001] The preparation of a plate type intelligent device for detecting sewage flow in a tank belongs to the technical field of automatic detection, and is specifically a sensor for detecting sewage flow. 2. Background technology [0002] At present, there are many technologies and products used in sewage flow detection at home and abroad. According to different measurement conditions and measurement purposes, the sewage flow meters currently used mainly include the following types: differential pressure flowmeter, positive displacement flowmeter, rotor type Flowmeter, hydraulic flowmeter, electromagnetic flowmeter, ultrasonic flowmeter, open channel flowmeter, etc. A brief introduction is given below: [0003] 1. Differential pressure flow meter [0004] The differential pressure flow meter is also called the head type velocity flow meter, which indirectly measures the flow rate by measuring the head difference. The main devices belonging to this type of flowme...
