Vortex Flow Meter
Insertion Version Typ: DVE
Our vortex flowmeter provides accurate and reliable flow measurement. In addition to the high-precision velocity sensor, the flowmeter includes a precision temperature sensor and a pressure transmitter. Thus it is possible to measure volumetric flow, mass flow, temperature, pressure, density and energy consumption with one device. The multivariable principle reduces complexity and cost compared to installing multiple individual devices to obtain the same process measurements.
The installation concept as an immersion probe allows easy installation via a weld-in socket. An additional advantage here is that with the use of the optional installation and removal device, the measuring device can be removed without interrupting the process.

Applications
Practical utilization areas for insertion vortex flow meters:
- In the chemical and petrochemical industry: monitoring and controlling the flow of chemicals injected into chemical processes for accurate dosing and reaction control. Measuring the flow rates of cooling water in heat exchangers and other equipment to ensure efficient temperature control in chemical and petrochemical processes.
- In the oil and gas industry: Monitoring flow rates in situations where multiple phases (oil, gas, and water) coexist in a pipeline, providing insights into production and well performance. Monitoring and controlling the flow rates of gas injected into oil wells for enhanced oil recovery.
- In the food industry: monitoring the flow of liquid ingredients in dough preparation processes, ensuring accurate mixing and consistency. Monitoring liquid flow rates during the mixing and blending of ingredients to ensure consistency. measurement of flow rates in the production of sauces, dressings, and condiments.
- In Pharmaceutical: Integration into continuous manufacturing processes to monitor and control liquid flows throughout the production line. Accurate measurement of liquid flow rates during the dosing and filling stages of pharmaceutical product manufacturing.
