一种高精度小流量双活塞式流量计

High-precision small-flow and double-piston type flow meter

Abstract

The utility model discloses a high-precision small-flow double-piston type flow meter. The high-precision small-flow double-piston type flow meter comprises a piston shell, an ejector rod, a seesaw support, electrode supports, electromagnetic valves and a control portion. A partition plate is arranged in the piston shell. A liquid guiding hole is formed in the lower portion of the partition plate. A left piston and a right piston are arranged in the piston shell. Displacement conduction liquid is contained in the space between the left piston and the right piston. The ejector rod is arranged on the piston shell. The seesaw support is arranged on the piston shell. A seesaw is hinged to the seesaw support. The seesaw is in contact with the ejector rod. The two sides of the piston shell are provided with a discharging hole and a feeding hole respectively. The electrode supports are arranged on the piston shell. An electrode is arranged on each electrode support. The electrodes are connected with the control portion through a guide wire. The discharging hole and the feeding hole are connected with the electromagnetic valves respectively through conveying pipes. The electromagnetic valves are connected with the control portion through wires. According to the high-precision small-flow double-piston type flow meter, the measurement precision is high, errors are small, operation is easy, and reading is convenient.
