Q

The Metron4 has 4 inputs - they can be 4-20mA, 0-10 volts or volt free contacts.  It also has two optional relay outputs. In addition to 4 analogue inputs (4-20mA), there are expansion cards for pulse counting (5 channels) and RS232 and options to develop RS485 and CANBUS interfaces.

Q

Yes, we can. We have multi network sim cards for the Metron4 giving the best coverage even in rural locations and we offer fixed pricing across Europe and often beyond. The sim cards are extremely affordable and secure.

Q

There are lots of sensors proven with the Metron4 from many of the major manufacturers and the smaller ones too. Level, pressure, temperature, humidity and flow are the more common ones.

Q

Yes, we have a battery powered Metron4 . 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.

Q

Yes, we have a solar powered solution for the Metron4 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.

Q

Yes, we have mains powered Metron4 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.

Q

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 from Metron4, though the record is an equivalent of 13 years!

Q

Metron4 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.

Q

The Metron2 has been superceded and is no longer available. Powelectrics now recommend using the Metron4. Metron4 does everything that Metron2 did and offers several advantages, which are described here.
