Capacitance Water Level Logger
User Manual
A 32mm PVC pipe ( 37mm inside diameter) can be used as a stilling well as the logger housing is
sized to catch in the top of the pipe. It should have 6mm holes drilled every 20cm over the entire
length of the piece of pipe. This allows water to freely enter the well and helps to ensure that the
water level measurements are linear over the entire length of the sensor element. A kit can be
purchased in 1m lengths from Dataflow Systems at www.odysseydatarecording.com and also a PVC
logger cover can be purchased to disguise the logger.
Memory Storage Capacity
The memory is capable of recording at least 60000 records. The number of recording days before
the memory is full can be calculated using the following formulae. If continuous logging is enabled the
oldest will overwritten first. If continuous logging is disabled no more data will be collected.
Examples.
Interval (mins) Records per Day Recording Days
60 24 2500
30 48 1250
15 96 625
10 144 416.67
5 288 208.33
It is recommended to use the longest interval required as this reduces the collection time and speeds
up the graphing process.
