Ultrasonic flow meter for low flow rates of water-like liquids
- Interference free operation
- Long life cycle, no moving parts
- Insensitive to pressure peaks and particles in the fluid
- Wide independence to the inlet and outlet pipe diameters
- Analog (4..20 mA) and pulse output signals
Ultrasonic flow meters for low flow rates of water-like liquids
SONIC-VIEW SVM-110 is an ultrasonic flow meter for water and aqueous solutions. The compact, non-obstructive instrument operates on the basis of two ultrasonic transducers, mounted on the outer surface of a straight, stainless steel tube. The flow meter does not contain any moving parts, causes virtually no pressure loss and can be mounted in any position, requiring no straight inlet or outlet runs. Its sensor housing is IP54 protected.
The in-line ultrasonic flow meter has a nominal size of DN20 for flow rates of 5…110 l/min and is suited for operating pressures up to 16 bar(g). The instrument allows frequency and analog output proportional to the flow and features an additional alarm output. The alarm status is indicated by an LED and the alarm level can easily be adjusted by means of a rotary switch on the front cover.
