1.Introduction
HFW3000 is an economical electromagnetic mainly used in water applications (electrical conductivity <20uS/cm). The HFW3000's electronics (convertor) comes with several syles in both integral or remote configuration. Remote communication can be obtained by a base-station type radio communication network system, with the use of a base station built in the central area, coverage radius can be as long as 500m. Base stations within a closer distance (SRD mode), can be used by an opened frequency range of 928 MHz   Base stations, Modbus communication network, can transmit  data to any central office. HFW3000 is designed with an IP65 OR IP68, die-cast aluminum enclosure which is particularly applicable for damp environment or underground mines.
