Pressure and flow sensors are devices that measure the force exerted by a fluid and the rate of fluid movement, respectively. They are crucial in various applications, from HVAC systems to industrial processes, for monitoring and controlling fluid dynamics.
Product Overview
DPA+ LoRaWAN® – Differential Pressure and Volume Flow Transducer
Differential pressure transmitter for measuring and monitoring overpressure, underpressure, differential pressure and flow volume of air and other non-aggressive gases in fan and filter systems in duct applications. Eight adjustable pressure and flow volume ranges permit use in HVAC applications of clean rooms, process measurement and controls systems. In addition to LoRaWAN®, additional analog voltage outputs are available as interfaces. In radio-shielded mounting locations, an optional external antenna can be used to optimize the radio link between the device and the gateway. A hinged cover and tool-free wiring as well as removable cable entries ensure a quick and easy installation. 'Dual' versions with two independent sensors for up to 2x differential pressures or 2x flow volume in a single enclosure are available. The mounting base (included in the delivery content) can be used to mount the DPA+ on a flat surface or on DIN rail TS35 (35x7,5 mm) in accordance with EN 60715.

CubicMeter LoRaWAN® – Non-invasive Volume Flow and Leakage Sensor
CubicMeter is a non-invasive volume flow and leakage sensor that was developed for use on copper and plastic pipes. Using ultrasonic technology, the sensor measures the volume flow and detects leaks without having to open existing pipework. It is mounted directly on the pipework using stainless steel clamps. The device transmits the detected data wirelessly via LoRaWAN®.
