1. Description

FlowVis Digital is the latest and most significant upgrade to date to the renowned FlowVis family. By adding Digital functionality

to the already unrivaled accuracy and flexibility of FlowVis flow meters, users will now experience even greater functionality, ease

of use, and precision. Unique features such as Pool Turnover Rate and an ability to set flow rate alarms, will further enhance the

industry's most respected flow meter.

FlowVis Digital employs a patented electronic design to accurately measure the flow rate. A remote digital display, housed in a

NEMA 4X corrosion proof enclosure, displays the flow rate in both a numeric value as well as in a bar-graph format.

Even with the ability to install FlowVis in tight spaces and with almost zero straight pipe requirements, it can sometimes be difficult

to install the device in a location that makes it easy to read. FlowVis Digital solves this problem by allowing you to install a Digital

readout in a user accessible location.

In addition to greater installation flexibility, the Digital upgrade will also eliminate the possibility of experiencing a parallax error

issue when reading the standard FlowVis.

Note: Parallax error can be caused by not looking at the FlowVis scale squarely – akin to a passenger in a car looking at the

speedometer and seeing a different reading to the driver. Additional details relating to this, can be found in the FlowVis Operating

Manual.

Using the 'Advanced Setup' features, FlowVis Digital can be interfaced with other systems such as heaters, chemical feeders and

UV units, so that they will only operate above a user-defined flow rate. When using this option, it will be necessary to include the

Auxiliary Interface Unit with your purchase.

FlowVis Digital also includes a 4-20 mA output that can be interfaced to Variable Frequency Drives, such as H2flow's

Eco-Flow in order to achieve constant flow control.

IMPORTANT INSTALLATION NOTE

installation. This section details the need for a Windows-PC with internet connection to complete an advanced setup.

FlowVis Digital is designed to be included (as an option) with any new FlowVis installation. Alternatively, it can be retrofitted to

an existing FlowVis – regardless of the size or model. For retrofit installations however, it is important to take careful note of

sections 6.1 and 6.2 of this manual.

WARNING

ALL CONNECTIONS MUST BE MADE BY A QUALIFIED ELECTRICIAN. ELECTRIC SHOCK CAN CAUSE

SERIOUS INJURY OR EVEN DEATH.

a) Electrical: FlowVis Digital utilizes a 100-240VAC to 12VDC power supply that needs to be plugged into a

standard receptacle. The power supply cord should be firmly inserted into the receptacle, and a plug restraining clamp

should be added, if any of the FlowVis Digital's outputs are being interfaced to other equipment such as VFD's, Heaters,

Chemical Feeders or any safety related equipment.

b) Mechanical: The FlowVis Digital sensor housing should only be secured to the FlowVis lid using the two extra long 1"

(25mm) stainless steel Phillips head screws provided.

Installers should read the section 'Advanced Setup' prior to
