The invention discloses a micro elliptical gear flowmeter without a mechanical transmission system and a processing method thereof. The flowmeter includes a body, a front cover, a first elliptical gear, a first mounting shaft, a second elliptical gear, a second mounting shaft, two or more transmitting magnets, a sensor, a back cover and an electronic counter, wherein the first elliptical gear andthe second elliptical gear are engaged and are placed in a cavity of the body, the front cover is fixedly equipped with the sensor, the other end is embedded with the electronic counter, the sensor isconnected with the electronic counter, and the sensor corresponds to the position of one of the transmitting magnets. The flowmeter is advantaged in that the structure is simple, the size is small, weight is light, the profile is novel, metering precision is high, the flow range is wide, the flowmeter is suitable for occasions having small pipeline diameters and small flow ranges, metering precision can reach a 0.2 level (the error is + / -0.2%), and the flowmeter can be widely used in various industries with high requirements for metering precision, such as chemical raw material ratio, food filling, mobile gas station, etc.
Description
technical field [0001] The invention relates to an oval gear flowmeter and a processing method thereof, in particular to a miniature oval gear flowmeter without a mechanical transmission system and a processing method thereof. Background technique [0002] Oval gear flowmeter (also known as displacement flowmeter, gear flowmeter) is a kind of positive displacement flowmeter, and it is a kind of high precision flow meter. It uses mechanical measuring elements to continuously divide the fluid into a single known volume, and measures the total flow volume according to the number of times the metering chamber fills and discharges the volume of fluid successively and repeatedly. [0003] Most of the traditional stainless steel oval gear flowmeters use multi-stage cylindrical gear trains and sealed couplings to transmit flow information. This kind of flow transmission method mostly uses mechanical counters, with complex structure, many moving parts, difficult processing, and inco...
