WELKIN's WFU series of ultrasonic flowmeter using the time differential principle. The measured fluid by the two pairs of ultrasonic generator and receiver turbine flowmeter two channels, a channel downstream direction by emitting an ultrasonic wave turbine flowmeter how to sell, another channel by countercurrent ultrasonic waves. Because ultrasound during "downstream" and "upstream" turbine meters parameters used by the fluid to be measured at different times, and the fluid flow rate and the time difference ΔT to form a single-valued function. Therefore, the time difference ΔT measured flow rate can be calculated, then come to traffic volume. Plug-in electromagnetic flowmeter main technical performance indicators: Medium temperature: 0-160 ℃ Power consumption: <20VA Accuracy: 0.5-1.0 Level Working pressure: <1.6MPa Connection: flanged, threaded connection velocity measurement range :( 0.05-10) m / s measurement pipe diameter: DN (150-6000) mm turbine flowmeter ex Anhui Electric Group (certification), turbine meters provided by the Anhui Electric Group Company Limited. Anhui Electric Group Co., Ltd. (www.ahecable.com) is Chuzhou, bare wires and bare conductor products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
