摘要： PROBLEM TO BE SOLVED: To provide a capacitative electromagnetic flowmeter which is highly reliable, superior in moisture resistance and is vibration proof, suppressing eddy currents generated in an excitation magnetic path, as much as possible.
SOLUTION: The capacitative electromagnetic flowmeter is excited by a frequency which is higher than the commercial frequency and is equipped with a characteristics correction filter 8B, which corrects the gain frequency characteristic of the excitation current so as to have a flat part in the exciting magnetic flux wave form. In a detection unit 10, the electrostatic capacitance value between face electrodes 4A,4B and guard electrodes 5A, 5B is made smaller than the electrostatic capacitance value between detecting face electrodes 4A, 4B and a fluid 2 to be measured. The exciting coils 3A, 3B are fixed to a cylindrical yoke, being shielded electrostatically by coil fixing plates 9A, 9B. Fixing by grounding rings 1A1, 1A2 is performed with the cylindrical yoke and the two ends of a measurement tube 1 which is symmetrical with respect to the tube axis and to the electrode axes. In addition, fixing is effected by filling the entire interior of the detection unit 10 with epoxy resin.

摘要： PURPOSE:To prevent the damage of a memory and to attain the long lift of service by storing mark in the checksum storing addresses of a checksum storing nonvolatile memory obtained from prescribed lower-order digital of checksum calculated from a data storing nonvolatile memory. CONSTITUTION:When a writing is performed, data are stored in a data storing nonvolatile memory 1. A checksum is calculated from the memory 1 by a CPU 3. The written mark of the previous checksum storing address of a checksum storing nonvolatile memory 2 is updated to store a mark in a checksum storing address obtained from prescribed low-order digits of the calculated checksum. Next, the checksum is calculated from the memory 1 by the CPU 3, the stored data of the checksum storing address are read out from the low-order digital of the calculate checksum. Then, in a case that the mark is stored in the checksum storing address, an arithmetic procession is performed, further in a case that the mark is not stored in it, an error procession is performed to display the error of the checksum on an error display unit 4.
