Portable Flow Meter - PORTALOK 7S
The Portalok 7s (original version) is a flow meter that is still very much in production because of its overwhelming popularity in the field.
One of the advantages of the Portalok 7S ultrasonic flow meter are its proven track record and its thousands of reliable measurements in almost every imaginable clamp on flow application. The flow meter is extremely popular in flow surveys because of its ability to conduct speedy measurements with minimum user knowledge. Failing on flow measurements can be very time consuming and frustrating for the actual end users and operators of the equipment who want reliable and easy to use (EASY FLOW) flowmeters. The EESIFLO® Portalok 7S ultrasonic flow meter does exactly what most users want in a fraction of the time it takes for others but also provides accurate and meaningful results.
