ANY LIQUID – ANY PIPE – ALL THE TIME
For the past 15 years, EESIFLO has helped thousands of plant operators, engineers and technicians successfully measure the flow of all possible fluids through every type of pipe from 1/2 inch to 100 inches in diameter, without cutting into their pipes or shutting down their processes. The term “downtime” is not part of our vocabulary.
Our battery operated Portalok ultrasonic clamp-on flow meters are currently being used in every corner in the world, in hundreds of diverse applications. We have seen your application many times in the past, and our Portalok will solve your flow measurement problems immediately. |

WHY CHOOSE THE PORTALOK ?
EESIFLO listens carefully to the recommendations of our clients and our Portalok 7SZ is the “Next Generation” of our powerful Portable, Clamp-On Ultrasonic Flow Meter, designed by users just like you.
The Portalok 7SZ will collect data for several days from remote locations, under extreme conditions, on a single battery charge. Close the lid and you’ll remove any chance of water invading the electronics or harming the sensors.
BATTERY MANAGEMENT Spare batteries are never a problem because the Portalok 7SZ uses standard rechargeable batteries, saving you time and money. |

ROBUST AND ACCURATE FLOW SENSORS
 |
|
EESIFLO employs the finest PEEK (polyether ether ketone) during manufacture of our transducers, thereby maintaining stability, accuracy and repeatability over a temperature range of -22 to 266°F (-30 to 130°C). Optional “High Temperature” sensors are available on request. Our sensor housings are entirely stainless steel, guaranteeing the most robust sensors in the industry.

MULTIPLE INPUTS / OUTPUTS WITH BUILT-IN DATA LOGGING
The standard Portalok 7SZ comes with a single user adjustable 4 to 20 mA output for connection to remote instruments, plus a single relay output which can be used as a counter or configured as an alarm at user defined values. There are numerous optional inputs and outputs defined in our specifications documents.
The standard Portalok has the ability to store one million data records, which can be downloaded to your computer with our EESIDATA software to help you analyze data and generate reports.
ADVANCED PROCESSING WITH REYNOLDS NUMBER CORRECTION
The Portalok 7SZ uses state of the art advanced processing electronics and data manipulation techniques which have been developed over many years measuring numerous clean and dirty fluids. Coupled with these techniques are built-in data tables enabling users to select from pre-programmed lists of liquids and pipe types. As long as you know the outside diameter and wall thickness of your pipe, and what kind of fluid you’re measuring, the Portalok will do the rest. |
