We are currently expanding our electronics range to include monitor devices. We are nearly exclusively a wholesale business and OEM supplier to the RV and Marine industries and we do not fit anything we sell. All the products we distribute are either our designs or we are the exclusive Australian and New Zealand distributor.We are currently trying to source a LPG Gauge or LPG flow meter. They will be used in caravans, camper trailers, motorhomes and boats. The normal size bottles are 4Kg or 9Kg. They can be either presure operated or Battery 12V/24V DC.Please let me know if you are able to help or need any more information.Thank you
