FAQ
Q: Are you a trading company or a factory?
A: We have been focusing on ultrasonic flowmeters for 32 years and we are a well-known manufacturer integrating R&D and factory.
Q: What types of pipes are compatible with the E3R flowmeter?
A: The E3R supports carbon steel, stainless steel, copper, and PVC pipes with outer diameters ranging from DN20 to DN80 mm. Please refer to the pipe size chart in the manual for exact OD ranges.
Q: Does the E3R require pipe cutting or process shutdown for installation?
A: No-E3R is a clamp-on meter; it installs in minutes without cutting the pipe or shutting down the process.
Q: How is the E3R powered and how does it communicate?
A: The E3R runs on 10–36 VDC and talks via RS485/Modbus and 22 dBm LoRaWAN, and it clamps on in minutes-no pipe cutting, no flow shutdown.
Q: What is the measurable flow range and accuracy?
A: The E3R measures flow velocities from 0.03 to 5.0 m/s with an accuracy of ±2% in the range of 1.0–16 ft/s (0.3–5.0 m/s). Repeatability is 0.2%.
