ANTI-CORROSION ELECTRIC TRANSMITTED-HIGH PRESSURE FLOW METER

A kind of anti-corrosion remote electrotransmission high-pressure flow meter is composed of sensing measuring unit, signal conversion unit, microprocessor system, and electric power supply system. It is to apply microprocessor to telecontrol a magnetoelectric sensing detector installed in high-pressure fluid pipe line, also to do sampling of the amount of fluid flowing over the measuring section, then according to the set up program to process and display the sampled electric signaling data, and according to established forms to printout the instantaneous and summing-up amount of flow at a regular interval of time. Said flow meter may be used in salt industry, chemical engineering, light industry, petroleum industry, etc. to teletransmit the measured flowing amount of containing acidic, basic and corrosive fluid such as salt bittern. It has features of strong corrosion-resistance, quick transmission and high accuracy in measuiement.

Alignment device for mounting of distribution-box copper bar and alignment method of alignment device

The invention relates to an alignment device for mounting of a distribution-box copper bar. The alignment device comprises a U-shaped clamp. An iron block is embedded in the inner side of the end of a left rib arm of the U-shaped clamp, and a magnetic column is correspondingly embedded in the inner side of the end of a right rib arm of the U-shaped clamp. The magnetic column is matched with a first mounting hole in a distribution box and a second mounting hole in the copper bar. A spring convenient to clamp is fixedly connected between the left rib arm and the right rib arm. The invention further relates to an alignment method of the alignment device for mounting of the distribution-box copper bar. Through mutual attraction of the iron block and the magnetic column on the U-shaped clamp, the mounting holes of the distribution box and the copper bar are mutually aligned. The device is simple in structure and convenient to operate.
