Sensor Hub Water Level Monitoring is a solution that is designed to respond to any solution where liquid level monitoring is needed.
The water level sensor is made from stainless steel with rigid and robust construction. The exquisite sealing technology as well as good assembly techniques guarantee the ULB16 level sensor’s outstanding quality & performance.
This solution can be widely applied in the petroleum, chemical industry, medicine, metallurgy, hydrology exploration, water tank level measurements, sewage, etc.
The Splitter cable can connect several Sensor Probes and Probe IOs to a single Sensor Hub port. The distance between the Sensor Hub and Sensor Probe/Probe IO can be extended via the Extension cable.
Note: Sensor Hub with Sensor Probe IO and connected sensor cannot be powered on batteries. You need to use the included power supply only.
The Sensor Hub has two variants based on the communication type - LoRaWAN® only and LoRaWAN®+NB IoT. SensorHub's NB-IoT module supports two types of LTE (Long-Term Evolution) categories, namely CAT M1 and CAT NB2. CAT M1 offers higher data rates and lower latency, while CAT NB2 provides ultra-low power consumption and greater coverage, making it an ideal choice for devices that operate on batteries and require long-term connectivity.
