Does anyone know if there are any power meters rated for wet environments. I am looking for something of the type that plugs into the power point then has a plug go into it. I would like to monitor the power usage of some pool pumps and chlorination. Currently I have been able to do this on parts of the day when the area is dry and only temporary. Often the area where the pump plugs in has water dripping on it.
Ideally the meter would be something like http://www.jaycar.com.au/productView.asp?ID=MS6115
but more able to stand water and more accurate. I want something that stores power usage while its turned off and later back on. (the pool pumps are run on a timer)
In case anyone is wondering the pool pumps are IP44 / IP55 rated and the power points are also rated for wet conditions are are mounted on wood off the pool water.
*IP 44 = protected against objects greater than 1mm Most wires, screws, etc, Water splashing against the enclosure from any direction shall have no harmful effect. - http://en.wikipedia.org/wiki/IP_Code.
The area gets wet through a number of ways: watering system above leaking water, rain including on days after it has stopped raining when the pool has too much water. Additionally water from the pool likely gets to this area.
I have been able to estimate the amount of power used based on the hours the pump runs / measured power but these estimates are not exact. Also if the timer gets changed / the power is run for longer the amount of power usage per quarter varies significantly.
I will likely be getting a meter put on the entire pool circuit in not too long but was wondering if any devices exists to measure the individual devices.
