The Metron2 has 4 inputs - they can be 4-20mA, 0-10 volts or volt free contacts.
Yes, we can. We have available multi network sim cards giving the best coverage even in rural locations and we offer fixed pricing across Europe and often beyond. The sim cards are nice and secure.
There are lots of sensors proven with the Metron2 from many of the major manufacturers and the smaller ones too. Level, pressure, temperature, humidity and flow are the more common ones.
Yes, we have a battery powered Metron2. We can fit a D cell sized battery that has a lot of power. Please note they are special batteries and you need to contact Powelectrics about replacements.
Yes, we have a solar powered solution for the Metron2 that has been shown to be able to support transmissions every 10 minutes from England. The package includes an intelligent charger which compensates for temperature as well as having ways to help deeply discharged batteries get back to life.
Yes, we have mains powered options available from simple “plug in the wall” type power supplies through to some DIN rail mount versions and even some with battery backup included with mains fail monitoring.
This depends on the regime, i.e. how often readings are being taken, how much power the sensors need and for how long, and how often readings are being transmitted. There are external factors which will effect battery life such as temperature and the local network conditions but in general if we are taking a reading once per day and sending it then we get around 4 years, though the record is an equivalent of 13 years!
The Metron2 is IP67 and designed to be mounted outside, exposed to wind, rain and whatever else. You need to make sure you follow the instructions for mounting the unit including fitting the covers over the mounting screws and fixing the lid down securely but not too tightly.
You can! In fact many of the units, out in the field, are currently mounted underground. Our Metron2 was even put to the test and where many had failed, WE SUCCEEDED! Read more about our underground testing in the blog post below.
This week a colleague of mine was invited to undertake some tests to see how our devices worked when installed under manhole covers. We were told to expect poor results as others had struggled in the past but the device performed really well. We were presented with 3 types of manholes (light, medium & heavy) and we did some testing with both GSM (GPRS) and 169MHz radio equipment.
Things went really well with us being able to communicate from beneath all three types on manholes with both GSM (GPRS) devices and the 169MHz radio kit.
So why is it we have succeeded where others have failed..? First of all with the GSM (GPRS) equipment we have a well tuned antenna but more importantly we do some clever power management making sure the GSM device gets plenty when it needs it...
