Moving particles generate a frequency shift proportional to the velocity of the particles
    • One sensor for Doppler measurement + piezoresistive pressure (depth) measurement +temperature compensation
    • Wedge sensor for mounting on channel bottom
    • For use in slightly to heavily polluted water
    • Flow velocity range; ±600 cm/sec
    • Level range; 0 - 350 cm

Level measurement using ultrasonic sensor

Ultrasonic pulses are reflected by the surface and received at the sensor. A common application is for depth v flow-rate determination on weirs and flumes.
    • Typical application is for monitoring sewer overflows at times of excessive rainfall when sewerage may be discharged into the environment
    •  Range up to 3 metres
    •  Deviation; ±4 mm or <0.2%
    •  4-20mA interface to logger

Level measurement using radar sensor

Sensor uses pulsed microwaves enabling high accuracy over a wide range. Furthermore, it is not affected by humidity, surface foam, etc., creating false echoes.
    • Accuracy; ± 2 mm (of reading)
    • One device covers wide range (up to 15 metres)
    • No dead-band under sensor (ultrasonic 250mm deadband, 6m range)
    • Not affected by temperature, humidity, surface foam, dust and air movements
    • Low maintenance costs
    • No drift and no recalibration

Overflow sensor

The overflow sensor is self-powered and, when submerged, indicates presence of water. The system measures the time an overflow occurs, e.g. over a weir. Installation of the sensor is made in the required position to detect an overflow. The sensor has a designed profile to avoid sediment build up.]]> Downloads

Applications include;

    • Storm weir overflow
    • Detection of a tank overflowing
    • Level detection in waste water chamber
    • Alarm on threshold of water
