    Telemetry tank lavel sensor measure tank level using “non-contact” technology that looks down at the water from above. These sensors are used in open air and in stilling tubes that constrain the sound and improve performance. Easy installationuse, reliable accurate report and remote access system make everything easier..For more details telemetry tank level sensor
