ULTRASONIC water level controller

ADVANTAGES

·         Simple installation and operation

·         No moving parts

·         Non-contacting measurement

·         Continuous water level detection

·         Can be used some non-liquid materials/media

·         Suitable for liquid and some solids

·         High accuracy & sensitivity

DISADVANTAGES

·         Turbulence in water can potential cause temporary inaccurate readings (not common)

·         Costs a little more than other types of water level sensors (more circuitry involved, high frequency transducer, etc)

·         May be difficult to sense levels at long range (most applications require only a short range)

·         Not appropriate for materials or tanks that can hamper the sensor’s received echo (odd shaped tanks, divider plates can throw off the signal, etc)
