The flow meter sensor outputs pulse of a variable frequency that is proportional to the rate of fluid flowing through the pipe. The number of litres flowing through the sensor can be calculated by ...

There are many water flow measurement techniques as well as different types of water flow meters used to measure the volume of water flow in pipelines but these all are too costly. This article ...

Arduino sketch which uses a flow meter and 3 onewire dallas sensors to measure various boiler functions and publishes them with mqtt - CrappyTan/FlowMeterDIY ...

Circuit diagram of the water flow meter is shown in Fig. 1. The circuit is built around Arduino Uno board (Board1), 16×2 LCD (LCD1), and water flow sensor YF-S201 (SENSOR1).

We have designed an IoT based water flow meter. It is powered by the ESP32-S3 SoC from Espressif. We have used an ESP32-S3 Wroom 1 module for the project which will be much easier to handle when ...

Neil Hannay explains how to understand flow meter sensor and pulse output types for efficient system operation FLOW meters have developed into many forms over the years, from mechanical devices – such ...

We introduce a flow meter to monitor the flow rate of individual phases in gas-liquid flows. The meter combines pressure data from a Venturi tube and void fraction data from a twin-plane capacitive ...
