Abstract

The invention discloses a portable spring flowmeter and belongs to the technical field of sewage flow measurement in sewage treatment. The portable spring flowmeter comprises a cylindrical casing, a handle with external threads, a spring, a grating ruler displacement sensor, a sealing piston and an electronic display screen, wherein the spring is arranged in the cylindrical casing, one end of the spring is connected with the cylindrical casing, the other end is connected to the sealing piston located in the cylindrical casing, and the grating ruler displacement sensor is arranged at the bottom of the cylindrical casing and connected with the electronic display screen located on the handle with the external threads through signal wires. By use of the principle that elastic deformation of the spring and impulsive force generated by water flow speeds are directly proportional, the flowmeter converts elastic deformation, caused by the impulsive force of water flow, of the spring into the flow speeds and calculates the flow by multiplying the flow speed and the sectional area of a pipeline, defects of a conventional flowmeter are overcome, and the purposes of accurate and timely measurement, little interference and portability are achieved.

Description

technical field [0001] The invention relates to a portable spring flowmeter, which belongs to the technical field of sewage flow measurement in sewage treatment. Background technique [0002] In sewage treatment, the influent flow and return flow are important parameters for operation regulation. Therefore, flowmeters are important equipment in sewage treatment plants. Whether the flowmeter measurement is accurate, timely and convenient directly affects the effect of operation regulation. The commonly used electromagnetic flowmeter measurement The environment is relatively harsh. When measuring viscous liquid with dirt, the sticky substance or sediment adheres to the inner wall of the measuring tube or the electrode, which changes the output potential of the transmitter and causes measurement errors. The dirt on the electrode reaches a certain thickness, which may cause The instrument cannot measure, and the ultrasonic flowmeter has poor anti-interference ability; it is easi...
