LUGB series Vortex flow meters are designed for measuring the volume/mass flow of liquids, gases and steam based on Karman vortex principle. Adopting advanced differential algorithm along with measurement of isolation, shielding and wave filtering, LUGB series vortex flow meters have the advantages of immunity on vibration and noise. Meanwhile, the liabilities of LUGB series vortex flow meters are well guaranteed by unique sensor packaging technology. Upon receipt, examine your meter for visible damage. The Vortex is a precision measuring instrument and should be handled carefully. Remove the protective plugs and caps for a thorough inspection. If any items are damaged or missing, contact us. Make sure the Vortex flow model meets your specific needs. For your future reference, it might be useful to record this information on nameplate in the manual in case it becomes unreadable on the Vortex. Refer to the nameplate for your customized product's specification.
