Managing liquid levels in tanks is critical in many industries across Kenya—from water supply and agriculture to manufacturing and oil storage. Level sensors help monitor the amount of liquid inside a tank, enabling efficient usage, preventing overflows, and ensuring safety. This guide dives into the types, benefits, applications, and suppliers of tank level sensors in Kenya.
Types of Level Sensors for Tanks
Ultrasonic Level Sensors
These sensors use sound waves to measure liquid levels without touching the liquid. They’re ideal for clean water tanks and corrosive liquids where contact is undesirable.
Float Level Sensors
Using a buoyant float attached to a switch or sensor, these provide simple and reliable level detection. Common in water tanks and fuel storage.
Capacitive Level Sensors
They measure changes in capacitance caused by liquid presence, suited for viscous or conductive liquids.
Radar Level Sensors
Radar pulses are emitted and reflected back to gauge level. These offer high precision and work well in harsh environments.
Pressure/Hydrostatic Level Sensors
Measure the pressure exerted by the liquid column to calculate level, useful for deep tanks and wells.
How Level Sensors Work
Level sensors operate by detecting physical changes such as distance, pressure, or electrical properties caused by the presence or absence of liquid. The choice depends on liquid type and tank conditions. For example, ultrasonic sensors bounce sound waves off the liquid surface, while float sensors physically move with the liquid level.
