Product Description

Product Overview:
 

HPM420L low power consumption level transmitter uses high quality stable pressure sensor as the measurement element, it measures the static level pressure accurately which has direct ratio with liquid depth. Then converting the measurement value into standard RS485 signal through the signal conditioning circuit to achieve the measurement of liquid depth. This product has extremely low power consumption and long service life with lithium-ion battery. The product has display, and with RS485 signal output, it can be networked or embedded with wireless module implement wireless transmission. With long-term aging and stability testing, the product is suitable for harsh outdoor environment and can be widely used for groundwater, rivers, lakes, surface water tanks, and inventory water tanks.
