Event logging
Data Transfer
All loggers may be configured to use GPRS or SMS remote communications for periodic reporting. Transmission period can be set from 15 minutes to 24 hours. The state-of-the-art antenna enables XiLog+ to operate from below ground in most locations. In areas of poor GSM/GPRS coverage an external antenna option is available.

Flow
The flow input can log two uni-directional flows or one bi-directional flow. Also, both outputs from combination meters can be logged on one logger input channel. Existing meter index value can be entered at start of logging. Operation with, but not limited to, the following flowmeters:

Pressure/Depth/Analogue
Accuracy to ±0.1% (of full scale). The offset of the transducer is corrected by the Auto Zero facility. XiLog 1P, 2i 3i have internal transducers. XiLog 2 accepts a range of electrical inputs or external pressure or depth transducers for monitoring weirs, reservoirs, and boreholes.

XiLog 9 has multiple digital, voltage and current inputs for flexible use in multiple applications.

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
