Ultrasonic water flow meter circuit diagram.

The receiver circuit fig 2 is built around a single decade counter cd4017 ic4 and a few discrete components. 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. The transmitter circuit works off 9 12v dc. The tdc gp30 ultrasonic flow sensor chip from ams is one of the module s major components.

Block diagram of basic flow meter figure 2 1 shows the flow meter concept block diagram. For larger diameter pipes sensors with multiple paths are used. Version of ultrasonic flow meters so that we usually call it version 13 flow meter. 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.

Jiangxi will employ water meter designs based on ams ultrasonic flow measurement solutions connected to the utility via an nb iot wireless network. Transit time measures the time differential between signals sent upstream and downstream. Both ultrasonic and traditional rotary meters benefit from low current consumption and integration that extend battery life and reduce system cost. There are two types of ultrasonic flow meter technologies.

The measuring device employed is ieslabs ia uwm 2 gp30 dn20 ultrasonic flow sensing module. The pcb board used in a tuf 2000m module is our 13. The circuit works from 9 12 vdc and can be used with batteries or a power supply. Ultrasonic flow meters are inferential meters that uses ultrasonic technology to measure the velocity of an acoustically conductive liquid moving through it.

The flow sensor is used to sense the flow of the gas or fluid. In addition to the integrated transducer style of ultrasonic flow sensor as illustrated in figure 1 for. Our integrated circuits and reference designs for water meters help you minimize energy consumption and maximize measurement accuracy. 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.

Accurate cost effective ultrasonic flow meters key a transformation in liquid and gas flow measurement. That is a nebulizer. The pcb board measures 116x62 millimeter. Doppler shift and transit time.

It generates pulses according to the flow sensed. These pulses are counted using a counter and then based on the number of pulses encountered in a. Very simple circuit desi. 2 1 basics of flow meter figure 2 1.

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. Of high performance general purpose ultrasonic flow meter heat meter ultrasonic flow converter.
