PURPOSE: A wire level transmitter is provided to easily remove and install equipment without inconvenience of loosing a bolt and removing a wire and empting a mud tank while re-installing and repairing equipment. CONSTITUTION: A wire level transmitter comprises a power supply unit, an electromagnet(8'), a hole(8''), an iron sheet, a microwave element(9), and a microwave-analog signal converting circuit(11). The power supply unit supplies power. The electromagnet is magnetized by being transmitted current through a wire from a power source. The electromagnet is inserted into the hole. The iron sheet surrounds the electromagnet. The microwave element radiates the microwave to measure a mud level of a mud tank. The microwave-analog signal converting circuit converts the reflected microwave by being radiated from the microwave element into an analog signal.
