Permanent Ultrasonic Flowmeter | GF U1000 V2

Permanent Ultrasonic Flowmeter | GF U1000 V2

Permanent Ultrasonic Flowmeter – Overview

This permanent ultrasonic clamp-on flowmeter is a cost-effective device that can either be used as a stand-alone meter or as an integral part of a control loop. The GF U1000 V2 Heatmeter (HM) is an ultrasonic permanent clamp-on heat meter/energy meter/BTU meter. The HM is equipped with Pt100 temperature sensors to calculate the energy of a heat-exchanging system. These flowmeters are very simple to install – clamp them onto the pipe, connect it to power and enter the pipe diameter. No expertise or special tools are required. This makes the installation of the sensors in running systems possible as the pipe does not have to be opened. Compact, robust and reliable. Designed for long-term use in industrial applications. The GF U1000 V2 (HM) is specially configured for pure water and can be used on PVDF-ABS, PVC, PP, PE, PB-Instaflex, iron and steel pipes. Processes can be monitored directly by a higher-level system via 4 to 20 mA, Modbus, pulse or frequency output. Suitable for use in ultrapure water measurement, flow measurement for heat metering, chilled water metering,  energy metering, monitoring of manufacturing processes and new Water / Glycol Measurement.
