Pressure, environmental sensing and flow measurement for HVAC, building automation and water applications in the Middle East.

The LEFOO team at Booth 3G88, showcasing sensing and control products for HVAC and industrial applications.
LEFOO participated in Big 5 Construct Saudi 2026 and the co-located HVACR Saudi Arabia, held from August 30 to September 2 at the Riyadh Front Exhibition & Conference Center in Riyadh, Saudi Arabia.
Exhibiting as Zhejiang Lefoo Sensing Technology Co., Ltd. at Booth 3G88, LEFOO presented sensing, control and instrumentation products for heating, ventilation, air conditioning and refrigeration (HVACR), building automation, water treatment and industrial process applications.
The display gave visitors a close look at pressure switches, pressure transmitters, differential pressure instruments and environmental sensors for their equipment and project requirements.
LEFOO's HVAC display brought together products for pressure monitoring, environmental measurement and airflow control. These product families support different functions in air handling units (AHUs), ventilation systems, refrigeration equipment and building management systems (BMS).

Pressure switches and damper actuators for equipment and air-handling control.
Air differential pressure instruments and temperature and humidity transmitters.
Mechanical pressure switches provide switching signals for equipment control, while differential pressure switches and air differential pressure transmitters can be selected for filter monitoring, fan status checks and pressure-difference measurement. Pressure transmitters provide continuous measurement for compatible refrigeration, pump and water-system applications.
Temperature and humidity transmitters, air velocity transmitters, CO and CO2 transmitters, and damper actuators formed another part of the product presentation. These categories address indoor environmental monitoring, ventilation measurement and air-handling control.
For OEM equipment manufacturers and system integrators, product selection starts with the application. Measurement range, output signal, supply voltage and installation requirements all need to match the intended control system.
Together, the displayed HVAC sensors and controls connect individual measurement tasks with wider building automation needs, from monitoring air filters and room conditions to managing ventilation equipment.
Alongside HVAC products, LEFOO highlighted industrial pressure transmitters, smart differential pressure transmitters and level measurement solutions. The display extended the presentation from building services to fluid measurement and process instrumentation.

LEFOO's Middle East application display featured municipal water, wastewater treatment, process control and seawater desalination. These applications require instruments to be selected against operating pressure, media compatibility, temperature and installation conditions.
Flow measurement also featured in the exhibition presentation, including electromagnetic flow meters for suitable conductive liquids. Combined with pressure and level instruments, flow meters expand the measurement options available for water treatment and industrial water systems.
For high-temperature, corrosive or hazardous environments, material choices, temperature limits and any required explosion-protection certification must be checked for the specific model and configuration.
At Booth 3G88, the LEFOO team welcomed visitors for face-to-face exchanges around the displayed products and their applications. The exhibition created opportunities to introduce the portfolio, answer product questions and explore future business cooperation.
