Flowtaker® is a unique, affordable single-patient uroflowmeter for home use. Home uroflowmetry can enhance conventional treatment, giving a better representation of the patient’s symptoms in their daily lives1.

Uroflowmetry at home

Male patients can use Flowtaker® in the comfort of their own bathroom, simply by placing the supplied urine container on top of the Flowtaker® before each void. It records every toilet visit for up to 2 weeks, with the accuracy of an in-clinic Uroflowmeter. A green light indicates the Flowtaker® is active, there are no buttons to press and nothing to be written down by the patient. The Flowtaker® is equipped with an internal clock and automatically collects a voiding diary.

Return by mail

At the end of the recording period, the Flowtaker® can be returned by mail or in person to allow the healthcare professional to analyze the results.

Analysis at the clinic

The supplied Flowtaker® software automatically collects and analyses flow traces creating nomograms, voiding diaries, statistical analysis summaries and customizable reports.

The Flowtaker® set

A Flowtaker® box contains all the supplies to serve up to ten patients/investigations, and includes the Flowtaker® analysis software.

After receiving the Flowtaker sensor at the clinic (or the GP’s office), all data can easily be downloaded with a USB-cable into the Flowtaker® software program.

Patient database

The Flowtaker® software has a patient database to store the Flowtaker® data. The database can easily be searched for date, ID, date of birth, and Flowtaker® device ID to find the requested study.


The software analyses multiple flow traces, giving a representative indication of the patient’s symptoms. Individual flow traces can be accessed via a Thumbnail overview window. A Frequency/volume page shows the automatically generated voiding dairy, also including total volumes per day. A Liverpool nomogram is available with all recorded uroflows and average shown in relation to the age corrected percentile curves. A supertrace window shows all uroflows and median in overlay mode. The statistics page shows results over all voids, 24h periods and nocturnal voids.


A customizable printable report can be easily generated and optionally includes a voiding diary, a nomogram, thumbnails of individual flows, supertrace plot, and statistics as desired.
