Compact Clamp-on Flow and Heat Meters

Clamp-on Flow Meters without the fuss.

Quick and easy to install, even by non-trained operators,  the clam-shell design of this range makes them a fast and reliable solution for non invasive flow and/or heat measurement applications. As the sensor seperation distance is fixed, there is no need for adjustment and once fitted they are not easily disturbed. 

• BFX3 Flow models and BEX3 Heat Meter versions
• 24V DC Powered
• Pulse Output, 4-20mA Output, Alarm Outputs
• Modbus RS485 Comms
• DN15 to DN90 (9 models)
• No need for tubes of ultrasonic grease, rulers and marker pens. Clean, hassle-free installation !
