Equipment Configuration:flowmeters for agricultural irrigation

Agricultural irrigation flowmeter based on the flow rate - water level operation algorithm, and the use of advanced servo water level tracking speed measurement system and microprocessor, so as to ensure the accuracy of speed measurement and calculation of a new type of intelligent flow system.

Project Overview

According to the width of the channel and the requirements of measurement accuracy, the mathematical model of open channel flow measurement is adopted by one-line one-point method or multi-line one-point method. Farm irrigation flowmeter has simple structure, no moving parts, strong resistance to dirt, blockage or corrosion, so it can be used in fluids containing suspended or bonded materials. Let's take a look at what to pay attention to in the installation and use of farmland irrigation flowmeter.

一、Ultrasonic probe installation methods and precautions

Farm irrigation flowmeter installation form of bracket installation and flange installation, if the site conditions allow the priority choice of flange installation, flange installation is more convenient to adjust the probe acoustic direction and the perpendicularity of the water surface. Due to the ultrasonic flowmeter launch angle and the existence of a blind spot, the water surface from the bottom of the probe to be greater than the blind spot distance, we can not choose the installation location from the edge of the channel is too close to the channel should be mounted on the channel above the centre line so as not to affect the normal operation of the instrument. Regardless of the type of installation, the probe into the line should be protected with a protective tube; probe launching surface must be exposed can not be blocked.

二、Ultrasonic Probe and Marshall Tank Fitting

The probe is mounted in the channel in a location that meets the requirements of the measuring weir tank. Marshall trough in the inlet contraction section of the 1/3 position, usually purchased Marshall trough will come with probe mounting bracket, only need to adjust the probe and level can be. Agricultural irrigation site many in order to save costs or to avoid transport trouble usually directly with cement poured into the water measuring trough, easy to cause the water level observation point at the water surface fluctuations drastically affect the water level measurement, this time you need to use the static water well, will be installed in the probe on top of the static water well, the construction of static water well. Due to the role of the connecting pipe, the water level in the static water well is the same as the water level in the water measuring weir groove. Requirements for static water wells for the square, the inner dimensions of 0.5 ~ 1 metre square is good.
