Modular Ultrasonic Flow Meter Specifications

1. Probe Type and Pipe Compatibility

Probe Type Pipe Diameter (DN) Installation Instructions

S-Type DN15100mm Small pipes (e.g. water supply pipes)

M-Type DN501000mm Medium pipes (e.g. industrial pipes)

L-Type DN3006000mm Large pipes (e.g. sewage pipes)

Warning: Probes cannot be moved after installation. For best performance, use a dedicated host for each probe type.
