液压传感间接测量水位计的研制及其应用

压力式水位计在水文自动测报系统中很难推广的主要原因是泥沙对传感器的影响,泥沙不但会使传感器测量精度达不到测验要求,而且由于泥沙淤积还会给水位计的日常维护带来很大不便。目前进口传感器测量精度高、稳定性能好,但仍避免不了泥沙的影响。针对这一问题,提出了一种新型压力式水位计———液压传感间接测量水位计,该水位计解决了泥沙对压力式水位计的影响,是一种具有很大发展前景的水位测量仪器。

Development and Application of Stage Indirect-gauging Recorder with Hydraulic Pressure Sensor

It is a main reason that the influence of sediment in river makes the pressure-type stage recorder difficult to be applied in automatic system of hydrologic data collection and transmission. The influence makes the precision of the sensor reducing and maintenance difficult. Although the import sensors have higher precision and good stability, they still can not keep from that kind of influence. Therefore, this paper introduces a new pressure-type stage recorder--stage indirect-gauging recorder with hydraulic pressure sensor. As a stage gauge that can keep from the influence of sediment, it has great development potential.
