Ultrasonic heat meter plays an extremely large role in the heating industry, then you know how to distinguish the quality of ultrasonic heat meter is good or bad? First of all, we choose qualified regular manufacturers, secondly, we can identify the quality of ultrasonic heat meter through the following aspects, let’s give you a detailed introduction:
Sensitivity: Sensitivity is the ratio of a small change in the output of the instrument to a small change in the input in a steady state; This is very critical;
Reproducibility: the reproducibility referred to here mainly refers to the degree of inconsistency of the shown value under the same condition, and the smaller the degree, the higher the accuracy;
Accuracy: according to the national unified provisions of the allowable relative error of the column standard value to grade. It specifies the maximum relative error of all levels of instruments under rated conditions of use shall not exceed the value;
Linearity: Nonlinear error, for the theoretical linear input and output characteristic curve of the instrument, the actual characteristic curve often deviates from the linear relationship. The percentage of the maximum difference between them relative to the range range is called linearity;
Stability: Indicates the performance of values that do not change over time and conditions of use. Time stability is expressed as stability, that is, the amount of random change in the value over a period of time. The effect of the change in the conditions of use is expressed as the effect error. For example, the influence of ambient temperature is expressed by how much the indication value changes for each change in temperature.
