Karman Vortex Wireless Flow Meter 4G Nb-Lot Lora Wirelesshart Protocol AES-128 Encryption No Moving Parts Digital Compressed DN15

A vortex flow meter works based on the Karman vortex street principle. When fluid (liquid, gas, or steam) flows through an orifice plate or a bluff body placed in the pipe, alternating vortices are generated downstream. The frequency of these vortices is directly proportional to the flow velocity. By detecting this frequency, the flow meter calculates the volumetric or mass flow rate. This principle provides reliable and repeatable measurement without moving parts.

A vortex flow meter can measure a wide range of media, including: Steam - Saturated steam, superheated steam Gases - Compressed air, natural gas, nitrogen, oxygen, etc. Low-viscosity liquids - Water, condensate, chemicals, light oils (viscosity typically < 30 cP) Note: Vortex flow meters are not suitable for high-viscosity liquids or slurries that may coat the bluff body and affect vortex generation.

The wireless vortex flow meter offers several key advantages: Advantage Description No moving parts Maintenance-free, no wear and tear No pressure-sensing tubing Eliminates clogging and leakage risks Battery powered No external power wiring required Wireless communication LoRaWAN / NB-IoT for remote data transmission Safe for hazardous environments No wiring means no spark risk in high-temperature or explosive areas Cost-effective Lower installation and maintenance costs compared to wired system

Our wireless vortex flow meters support the following industrial IoT protocols: LoRaWAN - Long range, low power consumption, ideal for factory-wide or city-wide deployment NB-IoT - Cellular-based, works in areas with mobile network coverage, good for remote monitoring 4G / LTE - Higher data rate, suitable for real-time applications WirelessHART - For integration with existing HART systems (optional) You can choose the protocol based on your local network infrastructure and application requiremen

Traditional flow meters require power cables and signal cables, which is difficult and costly in: High-temperature environments - Cables may melt or degrade Hazardous areas - Wiring increases explosion risk Remote locations - No power grid access Existing facilities - Retrofitting wiring is expensive The wireless vortex flow meter is battery-powered and transmits data via LoRaWAN/NB-IoT, eliminating all wiring. Installation simply involves clamping or inserting the sensor into the pipe and confi
