目前,测量油缸中的油品温度,都是用采样瓶将油品从缸内采出,再用玻璃温度计去测量;测量油缸下部水层高度,是用检水膏涂在有刻度的铜尺上,把铜尺垂直放入缸底,水就和检水膏起作用,使红色的检水膏变白,其变白的高度,即相当于水层高度.上述两种测量方法既不精确,又不方便.最近我们研制了一种测量 At present, the oil temperature in the measuring cylinder is obtained by sampling the oil from the cylinder with a glass bottle and then measuring with a glass thermometer. The height of the water layer in the lower part of the oil cylinder is measured by applying a water-based paste to a calibrated copper ruler , Put the copper ruler vertically into the bottom of the cylinder, and the water works as a water-repellent paste to turn the red water-based paste white and its whitened height, which is equivalent to the height of the water layer. , But not convenient.We recently developed a measurement
