由黑龙江省计量科学研究所研制成功的BWC-1型水泵温差测量仪获得黑龙江省科技进步奖,并获取计量器具生产许可证。该仪器是测量水泵进出口水温温差的专用仪器,具有数字显示、体积小、使用方便和能够自校正等特点,在油田、矿山、工厂和输油系统得到广泛应用。该仪器的测量原理是用A、B两只铂电阻组成桥路,当两只铂电阻所处环境温度不同时,桥线输出信号,该信号经过处理即可显示两处的温差值,还可测量A铂电阻处的温度。工作介质流经泵后,由于流体的摩擦和泵的损耗,介质温度升高,通过测量泵的进出口温差就可以确定泵的性能,用热力学方法测量水泵效率的关键是温差测量。因此,BWC-1型水泵温差测量仪是确定水泵性能必要的计量设备。主要技术指标:电源电压:220.AC±15%,
The BWC-1 water temperature thermometer, developed by Heilongjiang Institute of Metrology, was awarded the Heilongjiang Provincial Scientific and Technological Progress Award and obtained the production license of measuring instruments. The instrument is a special instrument for measuring the temperature difference between the water temperature of import and export of pumps. It has the characteristics of digital display, small size, easy to use and self-calibration. It is widely used in oil fields, mines, factories and oil transportation systems. The instrument’s measurement principle is to use A and B two platinum resistance bridge, when the two platinum resistance ambient temperature is different, the bridge output signal, the signal can be processed to show the temperature difference between the two, but also Measure the temperature at A Platinum resistance. After the working medium flows through the pump, the temperature of the medium rises due to the friction of the fluid and the loss of the pump. By measuring the temperature difference between the inlet and outlet of the pump, the performance of the pump can be determined. The key to measuring the pump efficiency thermodynamically is the temperature measurement. Therefore, BWC-1 water temperature measuring instrument is to determine the pump performance necessary measurement equipment. The main technical indicators: Power supply voltage: 220. AC ± 15%
