Magnetic induction pulse measuring water meter for measuring temperature and pressure

Abstract

The invention relates to a magnetic induction pulse measuring water meter for measuring temperature and pressure. The magnetic induction pulse measuring water meter comprises a water meter body, and further comprises a high magnetic induction stator piece, a thread stand core, a coil, an intelligent plate and a temperature-pressure sensor, wherein an upper cavity and a lower cavity are formed inside the water meter body; a water inlet is formed in the lower cavity; a water outlet is formed in the upper cavity; an impeller bottom base is arranged inside the lower cavity; an impeller top base is arranged inside the upper cavity; an impeller shaft is rotationally connected inside the impeller bottom base and the impeller top base; an impeller is fixedly arranged at the lower end of the impeller shaft; magnetic steel is fixedly arranged at the upper end of the impeller shaft coaxially; the temperature-pressure sensor is connected with the intelligent plate; the intelligent plate can be used for acquiring a pulse signal on the coil and used for converting the pulse signal into water flow information. As the magnetic steel is driven by the impeller shaft to rotate so as to generate the pulse signal from the coil, and the pulse signal is converted into water flow information, the water meter is high in measuring precision, accurate in measurement when water flow is relatively small, small in leaking loss, and beneficial to monitoring on water meter or pipeline fault as the water temperature and the water pressure can be measured by using the water meter.

Description

technical field [0001] The invention relates to the field of water meters, in particular to a magnetic induction pulse metering water meter capable of measuring temperature and pressure. Background technique [0002] More than 90% of the water meters used in daily life are mechanical meters. The traditional water meters have the following defects: 1. The measurement accuracy is limited. When the water flow is small, the leakage loss is large and it is difficult to measure accurately; 2. The measurement accuracy is low and the manufacturing cost is high; 3 .Using manual meter reading increases management costs, cannot measure temperature and pressure, and is difficult to monitor when a fault occurs. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a magnetic induction pulse metering water meter that can measure temperature and pressure. The water meter drives the magnetic steel to rotate through the im...
