LIQUI-VIEW BaseLVB-10-AD

Vortex flow meters with local display for monitoring low viscosity, water-like liquids

LIQUI-VIEW Base instruments are cost-effective Vortex flow meters for monitoring the flow or consumption of cleansing water, cooling water or spa water, operating on the vortex principle. The unique sensor body and IP65 protected transmitter design makes LIQUI-VIEW Base one of the most compact, lightweight vortex meters in the industry. The flow meters do not contain any moving parts, create just a low pressure drop and can be mounted in any position, requiring no straight inlet or outlet runs.

LIQUI-VIEW Base model LVB-10-AD has a nominal size of DN10 for flow rates of 2…40 l/min and is suited for operating pressures up to 12 bar(a). The instrument provides an analog output signal (4-20 mA) proportional to the flow and has a tilting display for local flow indication.
