HR8006 General Digital Water Level Transmitter

The HR8006 universal digital water level gauge is an input type water level measuring instrument with a stainless steel full-sealed structure, which greatly improves the reliability of the whole machine and can be put into the water for a long time. Since the circuit uses low-power devices, the overall power consumption is very low, about 4mA at full speed. This feature is very useful in situations where battery power is required.

1. Overview

The HR8006 universal digital water level gauge is an input type water level measuring instrument with a stainless steel full-sealed structure, which greatly improves the reliability of the whole machine and can be put into the water for a long time. Since the circuit uses low-power devices, the overall power consumption is very low, about 4mA at full speed. This feature is very useful in situations where battery power is required.

2. Features
þWidely used in freshwater drinking water treatment, waste water and sewage treatment, seawater measurement, surface water or groundwater monitoring in the hydrology and water industry.

þHigh stability liquid level measuring sensor element, good long-term stability

þRS485 standard MODBUS-RTU protocol, can be used in DCS or PLC system

þThe product also has reverse power protection and surge protection

þOptional unique air filter to prevent condensation and blockage in the atmosphere compensation capillary

þLow power consumption, when operating at full speed, the power consumption is about 4mA, which is outstanding when it is powered by an external battery.
