Our Metritape tank gauging systems and Metritape LA sensors are based on our unique, patented resistance-tape technology. A Metritape sensor is essentially an "electronic tape measure", which converts distance along its length into resistance, measured in ohms. The sensor backbone is a stainless steel strip with a gold contact stripe on the face. The steel strip is insulated on its edges and then wound with a gold finished nichrome wire to form a helix. When liquid contacts the sensor's outer envelope jacket, hydrostatic pressure causes the helix wire to contact the gold contact strip. The resulting resistance indicates the length of the active (uncontacted) helix, and the distance from sensor top to liquid surface. This no moving parts sensor resists product build-up and is not adversely affected by surface waves, foam or vapors within the tank.
