1. Equipment introduction:
Through continuous accumulation of production process technology, advanced mixed signal processing technology, and unique compensation methods, high-precision liquid level measurement products can achieve full range digital linear correction, full temperature range digital temperature error compensation, compensation parameters stored in non-volatile memory, and multiple safety protection mechanisms to avoid product failure due to calibration parameter loss; The circuit part is equipped with power monitoring and watchdog monitoring functions, and the mechanical part is a fully sealed stainless steel structure, greatly improving the reliability of the entire machine. Due to the use of low-power devices in all circuits, the overall power consumption of the machine is very low, with approximately 4mA at full speed operation.This feature is very useful in situations where battery power is required.
2. Application direction:
Widely used in freshwater drinking water treatment, wastewater and sewage treatment, seawater measurement, and surface water or groundwater monitoring in the hydrological and water conservancy industry.
