HR8003 pressure water level meter/intelligent water level and water temperature meter
HR8003 pressure water level meter is a hydrological instrument used for water level and water temperature measurement. It is developed through years of accumulation of production technology and using mixed signal processing technology. It overcomes the shortcomings of traditional analog circuit modules and can achieve full-scale digital linearity. Calibration,digital temperature error compensation in the entire temperature zone; compensation parameters are stored in non-volatile memory. The input-type structure is fully stainless steel sealed,and the product series is rich. It is widely used in water level and water temperature in industrial processes,,hydrology and water conservancy,geological exploration and other industries. Measurement.
