vortex shedding flowmeters for cooling water flow measurement Pipe size DN15-300

General introduction

The vortex shedding flow meter: when a fluid passes by an object or obstruction, oscillations can occur. Examples of these oscillations in nature include the whistling caused by wind blowing by the branches of trees, the swirls produced downstream of a rock in a rapidly flowing river, and the waving of a flag in the wind. Note that in all of these examples, when the flow is slowed, the oscillations stop. That is, the whistling stops when the wind dies down, the water flows calmly around the rock when the river is not flowing rapidly, and the flag does not wave in a mild breeze.

Technical data

Model selection

Calculation logic of gas work flow and standard cubic flow converting
Formula: pV=nRT
P-pressure, V-measurement, n-material weight, R-constant, T-absolute temperature
Under ideal gas status, unit: pa (pressure), m3, mol,k, R=8.31
It’s actually to convert work flow into standard cubic flow at 20 C, 101.325kpa.
For example, work temp. T=32C, work pressure:P= 0.6 Mpa, work flow Qw=100 m3/h, the standard flow Qs:
Qs=100 * (701325*273) / (101325*305)=619.5345 m3/h

Applications:

For air, natural gas, coal gas flow metering volumetric measurement in petroleum, chemical processing, metallurgy. Combined with our accumulator, it can measure the gas / air cubic flow or weight flow.

Competitive advantage:

• well education background staff
• wide field application experience, include but not limit to: oil field, petroleum, chemical process, environment protection, power grid, metellurgy, machinery, textile, etc
• complete manufacturing qualifications in flow instrument

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.
