Gas station underground tank measuring meter magnetostrictive fuel density sensor
What are Automatic Tank Gauge used for?
Automatic tank gauge are used for monitoring fuel liquid level, water level, density volume and temperature inside fuel storage tanks. It is widely used at gas station and skid-mounted fueling site. It also can be used at chemical factory, pharmacy industry and waste water tanks.
SP300D Magnetostrictive density sensor is mainly composed of probe head, temperature sensors, protection steel pipe, magnetostrictive waveguide wire and floaters with magnet inside. Insert probe into underground tank, floaters float on the liquid surface, and slides up and down on rod according to the changes of liquid level. Processing measured data of product level, water level, density values, and average temperature of five-points, then transmit these data to smart console by digital communication port.
