HR8000/K/RK Smart Liquid Level TransmitterHR8000/K/RK Smart Liquid Level Transmitter

HR8000 smart liquid level transmitter is a kind of input liquid level measuring instrument which realizes full-scale digital linear correction digital temperature error compensation in full temperature zone and stores compensation parameters in non-volatile memory adopting multiple security protection mechanisms. It avoids the problem that the product can not be used due to the loss of calibration parameters; the circuit module has power supply monitoring watchdog monitoring function and the input structure is all stainless steel sealed which greatly improves the reliability of the product.
The product performance is stable and reliable and it is widely used in liquid level measurement and control in industries such as hydrology and water conservancy municipal water supply petroleum chemical industry and geological exploration.
