Question: Would I serve to measure electric current of an industrial machine with a motor 230 volts and 4.1 amperes?
Document: It seems like a good device to monitor energy usage.After I turn on/off devices such as water heater/washer/dryer/a bulb, it immediately detects change in Kilowatt giving me a measure of energy the device uses.The sensor has 3 batteries, which are under a panel secured with 4 tiny screws. I winder why Owl owl would decide to do that rather than simply under a sliding panel. The newer models may not have that issue though. I have CM119A.
With this I was able to pinpoint what was running my electric bill through the roof. My submersible well pump was running 24/7! This device let's you see in real time how much electricity you are using. Love it!
I used the OWL electricity monitor in the UK to great effect - it worked perfectly.Unfortunately, when I purchased this one in the US - the monitors that clip around the mains power supply were not big enough to clip around the mains supply wires.Off to look for another monitor now. Before you order - measure the width of your mains supply wires to ensure that the monitor's clip on sensors will fit.
Bought one of these a year ago and altho it took a little learning to get it working correctly as the software is designed in England and is a little clunky, it now is keeping track of each one of the circuits in our home and I can tell how much energy for devices on any one circuit or the house in total, real time. It works on 240 VAC circuits as well as 120VAC circuits, one circuit at a time. It is necessary to get into the wiring panel to put the current sensors on the wires, and if you are not comfortable working in an electrical panel, its very easy for an electrician to do that.
I bought this unit to get a good idea of power usage.First problem was that the batteries do not last long.Second even when the batteries last the actual recording is very inconsistent. It skipped 2.5 months of data when I wanted to download the usage. All this while it was showing current usage all the time.Third, the software is absolute rubbish. Not user friendly at all and only gives one reading for three phase power instead of per phase.This is one of the worst tools/gadgets I bought.Bottom line it's junk, sorry.
I know now how much power the hot tub uses, how much the electric hot water heater uses, how much the furnace uses, etc. I was shocked to find out how much our houses uses when we "shut everything down" and go on vacation which then allowed me to make significant changes to reduce our energy consumption. The monitor works like a charm and provides data to your computer as well so you can track usage on graphs there. There are other monitors on the market, but at better than twice the cost of this one.
Installation is simple. We use the wireless unit half way across the house. If your wondering, you have to hook the sensors around the main power cables coming into your house. Preferably in the breaker box so the unit is not exposed to the weather. The 2 sensors connect to a wireless module that can be mounted on the wall that wirelessly transmits to the receiver. Range is good. I thought I knew how much power I was using based on the wattage draw of the major devices in my house and that wasn't adding up by vs what the electric company was charging.
Pros:Hooks up pretty easily if you are handy.Wireless connection seems rock solid.Manual says batteries will last 18 months.Keeps a running tally of your usage.Intuitive interface.Cons:Wish it updated a little faster (not a big deal though, still very usable) (guessing 1 update per 10s)Wish it could sync to my billing cycleOverall this is a very useful tool. I have already been staring at it and figuring out what it pulling the power and costing me money. My &#34;everything off&#34; usage seems to be about 500w, which tells me that I might have some work to do to find what is such a power hog around here.
I recommend this OWL monitor.
This helped me isolate what I wasn't taking into consideration and why my bill didn't add up to the $100 over it appeared that I was being charged. This was worth while for me. If you think your being overcharged, buy this. If you find you are being overcharged, give them a call with what your measuring and what they are billing you for.
Answer: yes
