Problems solved by technology

However, it has many deficiencies: such as mediocre measurement accuracy, high requirements for on-site installation conditions, large pressure loss, narrow range, etc.; in response to the above deficiencies, domestic manufacturers have introduced a series of improvement methods in recent years, such as integrated differential pressure flow Meter, fixed value throttling parts, replaceable orifice throttling device, standard nozzle, etc., plus two components of differential pressure flowmeter after the 1980s: differential pressure transmitter and flow display instrument have outstanding progress, so that such flowmeters will still occupy an important position

Abstract

The invention discloses a differential pressure type flowmeter capable of achieving remote monitoring, and particularly relates to the technical field of flow measurement, the differential pressure type flowmeter comprises a differential pressure type flowmeter body, a control PC terminal is arranged at the signal connecting end of the differential pressure type flowmeter body, and the connecting end of the control PC terminal is connected with a recheck terminal and a remote control terminal. According to the invention, the remote control terminal system logs in to check real-time information and the recheck terminal rechecks the proposed heart monitoring task, the identity information of the remote control terminal login person is confirmed in a three-party balancing restriction mode, the control PC terminal generates a new flow monitoring task after the identity is confirmed, and the three-party supervision mode is adopted. The mode of combining manual operation and data reading is adopted, the influence caused by data tampering by lawbreakers on traditional pure intelligent operation is effectively avoided, the interests of producers are protected, and the event that data of the differential pressure type flowmeter are tampered maliciously is eradicated.

Description

technical field [0001] The invention relates to the technical field of flow measurement technology, and more specifically, the invention relates to a differential pressure flowmeter for realizing remote monitoring. Background technique [0002] Differential pressure (also known as throttling) flowmeter is based on the throttling principle of fluid flow, and realizes flow measurement by using the pressure difference generated when the fluid flows through the throttling device. It is currently one of the most mature and commonly used methods for measuring flow in production. It is usually composed of a throttling device that can convert the measured flow into a differential pressure signal, a differential pressure gauge that can convert the differential pressure into a corresponding flow value, and a display instrument. In the unit combined instrument, the differential pressure signal generated by the throttling device is often converted into a corresponding standard signal (...
