Ultrasonic Flow Meter Handheld Flowmeter RS485 Ultrasone Flowmeter Sensor 4-20mA
Description of Ultrasonic Flow Meter Handheld Flowmeter RS485 Ultrasone Flowmeter Sensor 4-20mA
Ultrasonic Flow Meter Handheld Flowmeter RS485 Ultrasone Flowmeter Sensor 4-20mA has been upgraded based on the previous ultrasonic flow meter which is still the main product line of the company. The new Version retains most of the excellent features and functions of the previous versions: the pulse measurement technology, the ultrasonic igniting and the small signal receiving circuits etc. The main improvements are made on the battery supply circuit and on the transmitting circuits. All other circuits are simply integrated into this new version without major modifications, due to the fact that we have already applied the most advanced measurement technologies and attained a more reliable model of ultrasonic flow meter.
