1. What is the low flow rate cut-off value of an ultrasonic flowmeter?
The low flow rate cut-off value of an ultrasonic flowmeter refers to a threshold set by the manufacturer to ensure the accuracy of the accumulated amount of the flowmeter, which does not accumulate or display flow at low flow rates. Here is a detailed explanation of the concept
1. Purpose of setting: In practical use, when external interference occurs to the ultrasonic flowmeter, the flowmeter may have small flow displays, but these displays may not be accurate and are not generated by real fluid flow. In order to avoid the accumulation of inaccurate flow data and the occurrence of errors in the overall accumulation, manufacturers will set a low flow rate cutoff value. The specific function of the cutoff value is that when the measured flow rate of the flowmeter is lower than this cutoff value, the flowmeter will not accumulate flow or display this part of the flow data. This can ensure that the accumulated flow data is more accurate and reflects the real fluid flow situation. 3. Setting range of cut-off value: Generally speaking, the cut-off value for low flow rate will be less than 1% of the full range of the flowmeter. This setting range is based on a comprehensive consideration of various factors such as the measurement accuracy of the flowmeter, the degree of external interference, and actual application requirements. Note: When using an ultrasonic flowmeter, users should pay attention to understanding the low flow rate cutoff value of the flowmeter in order to correctly understand and use the flow data. If accurate flow measurement is required at low flow rates, it may be necessary to consider using other types of flow meters or taking other measures to improve measurement accuracy.
2. How much does an ultrasonic electromagnetic flowmeter cost?
The price range of ultrasonic electromagnetic flowmeters is large, and the core influencing factors include brand, specifications, functions, range and caliber. The specific price range ranges from 285 yuan to tens of thousands of yuan.
Price reference for mainstream products on sale - Basic universal type: such as spot wholesale ultrasonic water meter, priced at about 285 yuan/unit, suitable for measuring water flow in conventional small-diameter pipelines - High cost-effective industrial type: spot universal ultrasonic electromagnetic flowmeter, priced between 180-2250 yuan/unit - Anti corrosion customized type: intelligent electromagnetic flowmeter for wastewater slurry and sewage scenarios, DN50/100 specification, priced at about 379.5 yuan/unit - Imported brand type: US Weidun VTON imported model, DN1-1000 full specification coverage, priced at 1760 yuan/unit - High precision explosion-proof type: fixed external clamp wall hanging explosion-proof model, can measure liquids, gases, and oils, priced at about 1121 yuan/unit 2 The price influencing factors indicate that the functional differences of different products will significantly affect the selling price: models with remote digital display, anti-corrosion and explosion-proof, large caliber customization, and imported brands will be several times more expensive than the basic model.
