- Commodity name: High-precision vortex flowmeter
The vortex flowmeter is a volumetric flowmeter developed based on the Karman vortex street principle, used to measure the volumetric flow, standard volumetric flow, or mass flow of gases, steam, or liquids. It is mainly used for flow measurement of industrial pipeline media fluids, such as gases, liquids, steam, and various other media.

1. Simple and sturdy structure, no moving parts, high reliability, and very reliable for long-term operation.
2. Easy installation and very convenient maintenance.
3. The detection sensor does not directly contact the measured medium, ensuring stable performance and long service life.
4. The output is a pulse signal proportional to the flow, with no zero drift and high accuracy.
5. Wide measurement range, with a range ratio up to 1:10.
6. Low pressure loss, low operating costs, and more energy-saving significance.

Applicable Medium	Liquid, gas, steam (saturated steam, superheated steam)
Protection Level	IP65 (IP67, IP68 available upon agreement)
Operating Power Supply	24VDC±5%, lithium battery 3.6VDC (battery life greater than 2 years) optional
Range Ratio	When gas density is 1.2kg/m³, range ratio is 8:1; when liquid density is 1000kg/m³, range ratio is 8:1; range ratio varies with different medium densities
Environmental Conditions	-20℃ to +55℃ (standard type), relative humidity 5% to 95% RH, atmospheric pressure 86kPa to 106kPa
Accuracy	Gas without compensation: DN15-DN25--Class 1.5, DN32-DN200--Class 1.0, DN250-DN300--Class 1.5; Liquid without compensation: DN15-DN300--Class 1.0; Temperature and pressure compensation: DN25-DN300--Class 1.5
Signal Output	Instantaneous flow corresponding frequency pulse (low level ≤ 1V, high level ≥ 6V); isolated two-wire 4-20mA output corresponding to displayed instantaneous flow (E3 type); isolated three-wire 4-20mA output corresponding to displayed instantaneous flow (E4 type)
