The invention discloses a portable float type automatic tide gauge which comprises a filter tube, a float, a retardation filter and a central control unit. The filter tube is provided with a pluralityof magnetic control switches along the height direction thereof, and each magnetic control switch corresponds to a height position. The filter tube is provided with an opening. The float can float inthe filter tube. The float can trigger the action of each magnetic control switch. The retardation filter is arranged in the opening of the filter tube. Water flow can come into the filter tube through the retardation filter to enable the float to float. The central control unit is arranged on the filter tube, and the central control unit is connected with a number of the magnetic control switches. According to the portable float type automatic tide gauge provided by the invention, the height position of the float is reflected by the action of the magnetic control switches, so as to acquire the liquid level height in the filter tube and a tide level value; the retardation filter can filter the water flow, which can effectively weaken the interference of the kinetic energy of the water flow; and the measurement accuracy is improved.
Description
technical field [0001] The invention relates to the field of tide gauge equipment, in particular to a portable float type automatic tide gauge. Background technique [0002] With the development of electronic technology, various tide measuring instruments have appeared one after another. The existing tide gauges are divided into artificial tide gauges, pressure type tide gauges, ultrasonic tide gauges, laser tide gauges, GPS tide gauges, float type tide gauges, etc. according to their principles. [0003] The principle of artificial tide measuring equipment is to mark the scale value on the water gauge, and obtain the current water level value by manually reading the scale of the submerged water gauge. The advantage is that the measurement result is intuitive and reliable, and the disadvantage is that the degree error is relatively large when the swell is large. Large, manual observation is required. Artificial tide gauge equipment is usually used in instrument comparison ...
