The vortex type flow transmitter operates based on the principle of the "Von Kármán effect." This device is capable of withstanding high temperatures of up to 350°C while achieving a measurement accuracy of 1%. Its sensor is available in a choice of SS304 or SS316 materials. Equipped with simultaneous Modbus, 4–20 mA, and pulse output capabilities, it serves as the preferred instrument for measuring gases, liquids, steam, and thermal oils. As a highly durable device, it contains no internal moving parts, offering the distinct advantages of simple installation, convenient maintenance, and low maintenance costs.
How do you select the most suitable vortex flowmeter based on the characteristics of the measured medium?
1. If measuring media such as gases, saturated steam, superheated steam, or thermal oil, it is necessary to use a vortex flowmeter equipped with temperature and pressure compensation. Such devices can display flow rates in mass units-such as tons/h or kg/h-thereby ensuring measurement accuracy and stability. This is essential because the density of these media, and consequently their volume, fluctuates in response to changes in temperature. Instruments equipped with temperature and pressure compensation simultaneously display flow rate, pressure, and temperature; they automatically correct the readings based on variations in pressure and temperature to yield accurate measurement values.
2. If measuring media with stable densities-such as water or air-one may opt for a model without temperature and pressure compensation. This approach helps reduce procurement costs while still maintaining an accuracy level of 1%.

3. RFQ:
Q1. Are you a manufacturer or a trading company?
A1: We are a manufacturer. Our factory is located in Kaifeng, China, and has been in operation since 2002. We primarily manufacture and sell a wide range of industrial flow meters and related products. You are welcome to visit us!
Q2. What products and services can you provide?
A2: We offer comprehensive, one-stop services for flow measurement solutions. Our product range includes the sale of various industrial flow meters, industrial ultrasonic water meters, differential pressure transmitters, pressure transmitters, and other instrumentation.
Q3. What are your packaging terms?
A3: Generally, we select the most suitable and secure packaging based on the product's weight and the chosen shipping method. For equipment involving small pipe diameters-which tends to be lighter-especially when shipped via express courier, we utilize carton packaging with internal foam padding. For equipment with large pipe diameters-particularly when shipped via sea freight-we opt for wooden crate packaging.
Q4. What is your delivery lead time?
A4: We maintain a substantial inventory of raw materials and standard-configuration equipment. For standard models-specifically orders of 50 units or fewer-the estimated time required for production and calibration after order confirmation is 2 business days. For non-standard models, production times vary depending on the specific quantity and specifications; typically, this requires 5 business days. For more specific details, please consult with our sales representatives.
Q5. What is your Minimum Order Quantity (MOQ)?
A5: Our minimum order quantity is 1 unit.
Q6. How do you ensure high product quality?
A6: We have established a comprehensive quality control system. Prior to shipment to our customers, all our products undergo thorough inspection by our IQC (Incoming Quality Control) and OQC (Outgoing Quality Control) departments.
