DIFFERENTIAL PRESSURE TYPE FLOWMETER PROVIDED WITH PRESSURE-INTEGRATED TYPE SENSOR SIMULTANEOUSLY MEASURING PRESSURE AND DIFFERENTIAL PRESSURE

摘要

The present invention relates to a differential pressure type flowmeter and to a differential pressure type flowmeter provided with a pressure-integrated type sensor simultaneously measuring a pressure and a differential pressure, whereas a conventional differential pressure type flowmeter measures a differential pressure and a pressure by respective sensors to calculate a flow rate or to measure a water level within a pressure container and cannot simultaneously measure the differential pressure and the pressure by one sensor to make it difficult to save costs and to have restrictions in utilizing a space. The present invention provides the differential pressure type flowmeter, capable of simultaneously measuring the pressure and the differential pressure and measuring a flow rate or a water level, configured to include a Venturi tube (100) and a pressure-integrated type sensor (200). In addition, the present invention provides the differential pressure flowmeter capable of simultaneously measuring the pressure and the differential pressure and measuring the flow rate or the water level, in which the Venturi tube (100) includes an upper tube (110) and a lower tube (120), and the pressure-integrated type sensor (200) includes a high pressure sensor unit (210), a low pressure sensor unit (220), a calculation unit (230) and an output unit (240). In addition, the present invention provides the differential pressure flowmeter capable of simultaneously measuring the pressure and the differential pressure and measuring the flow rate or the water level, in which a communication unit (250) is added to the pressure-integrated type sensor (200) and a wireless or wired communication device is connected thereto to have a function of transmitting pressure information, flow rate information, water level information, etc., and receiving information for updating a calculation program mounted in the calculation unit.;COPYRIGHT KIPO 2020
