Description

High-precision evaporation detection equipment

Technical Field

The utility model belongs to the technical field of hydrological monitoring, and particularly relates to high-precision evaporation detection equipment.

Background

Hydrological evaporation test: namely measuring the evaporation depth of the liquid surface of the water surface within a certain period of time. Measured using an evaporator of specified area, in units of 0.01 mm. At present, the widely used evaporation test observation mainly adopts manual observation, and a few automatic test devices have two modes of float type liquid level test and weighing type test.

Float evaporation test mode: because the test precision requirement of the evaporation liquid level is 0.1mm, the liquid level variation is small, in order to improve the test precision, the area of a floating ball of a floater sensor (the diameter reaches 300 mm) needs to be increased at the same time, the area of the liquid level outside the test equipment is increased, the test equipment adversely affects the test precision (the conversion ratio is increased), and a contradiction that the test precision cannot be improved always exists.

The evaporation test device of weighing type weighs the amount of water evaporated from the container by an electronic scale and converts the weight into an evaporation value. The disadvantages are that: 1. the water supplementing measurement precision, the stability of the weighing device and other parameters related to weighing all influence the testing precision. 2. The weighing type evaporation test device has a complex structure, so that the failure rate is high in use.

The traditional evaporation test device can not meet the requirement of high precision, and manual intervention observation is needed, so that the measurement has larger error; therefore, the application provides a high accuracy evaporation check out test set
