Industrial Water Flow Meter Transit Time Type

Ultrasonic water meter and heat meter for industrial water flow measurement, Transit time type

Description:

The Ultrasonic water meters use sound waves to determine the velocity of a fluid flowing in a pipe. At no flow conditions, the frequencies of an ultrasonic wave transmitted into a pipe and its reflections from the fluid are the same. Under flowing conditions, the frequency of the reflected wave is different due to the Doppler effect. When the fluid moves faster, the frequency shift increases linearly. The transmitter processes signals from the transmitted wave and its reflections to determine the flow rate.

This transit time type, ultrasonic transmitter send and receive ultrasonic waves between transducers in both the upstream and downstream directions in the pipe. At no flow conditions, it takes the same time to travel upstream and downstream between the transducers. Under flowing conditions, the upstream wave will travel slower and take more time than the (faster) downstream wave. When the fluid moves faster, the difference between the upstream and downstream times increases. The transmitter processes upstream and downstream times to determine the flow rate.

Calibration equipment

Shanghai I Fluid Technology Co., Ltd, a technique based company. We focus on the deployment , installation and management system of smart metering and smart grid in all utility sectors, include but not limited to water, heat, gas and electricity.

To adapt to the global environment protection trends, and China government policy, China put the green energy application and EIA at their first place. We do our best contribution to the government energy saving policy.

We put emphasis on central air conditioning system, energy distribution system in separated areas, green energy application in commercial buildings, municipal water / gas / heat supply, sewage discharge monitoring, and many other industrial applications. Adhere to the principle of “ low carbon energy, build future”, we aim to give solution to take the best avail of natural resources, improve energy efficiency, reduce energy consumption. Through more renewable energy, reasonable energy store technique, and minimize energy demands, we help our clients to build an intelligent low carbon energy network. Build the optimized electricity, heat, water and gas supply and demands system, finally to realize the LOW to ZERO energy system.

Over tens of years developing, we design and manufacture a complete set of energy relating products: central air condition with variable ventilation and ventilate at low temperature, flexible central air conditioning, cooling store capacitor, AMR/AMI, metering and level products.
