MOUNTING
As shown in picture 1, when the submersible level sensor is installed in static water such as in poos, water towers, probe is immersed into the bottom and should be as far as possible away from the pump or valves. The terminal box should keep above water surface and prevent water penetrating into cables.Please make sure the airway not be blocked;
As shown in picture 2, when the submersible water level sensor is installed in dynamic water such as dams or rivers, the probe should be inserted into a steel pipe(inner dia is around 45mm), burrowing several holes at a different height on the pipe side wall which is opposite to the water flow direction. The terminal box should keep above the water surface and prevent water from penetrating cables. Please make sure the airway not be blocked.
PRODUCT APPLICATION
Applications of the Rika RKL-01 submersible level transmitter
Submersible water level sensors can be used in a variety of applications, including groundwater monitoring, wastewater management, and irrigation systems.
They can also be used in industrial applications to monitor water levels in tanks and other containers.
