The invention discloses a mobile phone adjusting system for an industrial flow meter. The mobile phone adjusting system comprises a flow meter indicator panel and a flow meter internal circuit, and is characterized by further comprising a mobile phone adjusting client, wherein the flow meter internal circuit consists of a Hall angle sensor, a singlechip microcomputer, a 24mA current loop module and a GPRS (General Packet Radio Service) module; the signal output end of the Hall angle sensor is connected to the signal input end of the singlechip microcomputer; the control end of the singlechip microcomputer is connected to the 24mA current loop module; the 24mA current loop is connected to a far-end computer; the output end of the singlechip microcomputer is connected to the GPRS module; the GPRS module is wirelessly connected with the mobile phone adjusting client. The mobile phone adjusting system has the advantages of convenience in use, easiness in comprehending and capability of effectively lowering the adjusting cost.
Description
technical field [0001] The invention relates to an industrial flowmeter adjustment system, in particular to an industrial flowmeter adjustment system using a mobile phone for wireless adjustment. Background technique [0002] With the development of economy and technology, flowmeter is widely used as a means of industrial control and detection. In actual use, in order to ensure the use effect, the flowmeter often needs to be adjusted. The general flowmeter is adjusted only when it leaves the factory or is installed. After the installation is completed, if adjustment is required during use, the flowmeter needs to be removed for adjustment, which is obviously troublesome, even if some specific adjustment equipment can perform online adjustment of the flowmeter through wired communication, but if The flowmeter is installed in a complicated environment, and such an adjustment method is not convenient. Therefore, it is necessary to provide a flowmeter adjustment system, which ...
