These miniature submersible-level transmitters have a long cable attached to a compact bullet sensor with a very small diameter. The sensor is lowered into tanks, wells, or down small boreholes to sense and convert pressure readings into electrical signals. These output signals are then sent through the cable to a control room or panel. They are often used for well, ground, and surface water monitoring, remote telemetry applications, remediation, and for narrow conduit or pipe installations and pump protection.
