Ultrasonic Water Flow Meter Circuit Diagram

Transit time measures the time differential between signals sent upstream and downstream.

Ultrasonic water flow meter circuit diagram.

The ultra sonic circuit is adjusted in such a way as to stay in balance as long the same as the output frequency of the transmitter. There are two types of ultrasonic flow meter technologies. Block diagram of basic flow meter figure 2 1 shows the flow meter concept block diagram. Ultrasonic flow meters are inferential meters that uses ultrasonic technology to measure the velocity of an acoustically conductive liquid moving through it.

Both ultrasonic and traditional rotary meters benefit from low current consumption and integration that extend battery life and reduce system cost. Of high performance general purpose ultrasonic flow meter heat meter ultrasonic flow converter. Critical for revenue collection leak detection and conservation of critical natural resources flow meters lie at the heart of utility and industrial distribution systems of water gas and heat. These pulses are counted using a counter and then based on the number of pulses encountered in a.

I designed humidifier circuit. It is encased in a. The tdc gp30 ultrasonic flow sensor chip from ams is one of the module s major components. It generates pulses according to the flow sensed.

How to make an ultrasonic humidifier ultrasonic humidifier or circuit diagram. In addition to the integrated transducer style of ultrasonic flow sensor as illustrated in figure 1 for. The measuring device employed is ieslabs ia uwm 2 gp30 dn20 ultrasonic flow sensing module. For larger diameter pipes sensors with multiple paths are used.

That is a nebulizer. The circuit works from 9 12 vdc and can be used with batteries or a power supply. To check the working of the transmitter it is necessary to down convert the 40khz signal into 4khz to bring it in the audible range. If there is some movement in the area covered by the ultrasonic emission the signal that is reflected back to the receiver becomes distorted and the circuit is thrown out of balance.

Version of ultrasonic flow meters so that we usually call it version 13 flow meter. Doppler shift and transit time. Ultrasonic water flow meter pipe the single path sensor of figure 1 is used for flow applications where the diameter of the pipe is small. Accurate cost effective ultrasonic flow meters key a transformation in liquid and gas flow measurement.

2 1 basics of flow meter figure 2 1. The flow sensor is used to sense the flow of the gas or fluid. The transmitter circuit works off 9 12v dc. The pcb board measures 116x62 millimeter.

Our integrated circuits and reference designs for water meters help you minimize energy consumption and maximize measurement accuracy. Jiangxi will employ water meter designs based on ams ultrasonic flow measurement solutions connected to the utility via an nb iot wireless network.
