REINVENTING a new concept of transit time ultrasonic flow sensor

Challenge

Today‘s technical standards for flow sensors require

measurements to be performed non-invasively and

through a straight tube for easy cleaning, thereby

avoiding both pollution of the fluid and sensor damage.

Moreover, demanding flow metering and monitoring

applications require both a short response time and

high flow-measurement accuracy.

Innovation

This challenge in mind, DIGMESA AG developed an innovative

new measurement device for medium to high flow

rates of 0.05 to 20 l/min, respecting strict fluid purity and

flow metering requirements. DIGMESA has interpreted the

well known ultrasonic time of flight technology in a new

way and presents this with its new ultrasonic devices.

Applications

Thanks to its technology and its measurement concept, the

new Digmesa Laser Flow-Sensor is perfect suited for handling

high-purity liquids in the semiconductor or chemical

industries. The almost straight tube made out of certified

plastics makes the device also a perfect choice for the food

and beverage marked.

Key Features

The Digmesa ultrasonic approach impresses with an easy

cleanable, almost straight measurement tube. The tube is

out of one piece and therefore no dead ends are present

and particle deposits may be avoided.

Despite all these mechanical advantages the Digmesa AG

Ultrasonic devices have no restrictions in the measurement

properties: huge dynamic range (0.05-20l/min) is given

as well as excellent accuracy.

LASER FLOW SENSOR

Challenge

Today‘s technical standards for flow sensors require

measurements to be performed non-invasively and

through a straight tube for easy cleaning, thereby

avoiding both pollution of the fluid and sensor damage.

Moreover, demanding flow metering and monitoring

applications require both a short response time and

high flow-measurement accuracy, impossible to achieve

using existing sensors.

Innovation

This challenge in mind, DIGMESA AG developed an innovative

new measurement technology for low flow rates, 1

to 60 ml/min, respecting strict fluid purity and flow metering

requirements. DIGMESA has designed a totally noninvasive

and non-intrusive measurement concept involving

a laser beam crossing a straight glass tube through which

the fluid is flowing.

Applications

Thanks to its technology and its measurement

concept, the new Digmesa Laser

Flow-Sensor is perfect suited for handling

high-purity liquids in the semiconductor,

chemical or medical industries.

Key Features

The new liquid flowsensor technology, consists in a laser

oriented perpendicular to the media flowing through a

straight glass tube. The innovative, non-intrusive sensor

concept allows measurement of flow-rates in the 1-60ml/

min range with response times of ~50ms and accuracies

better than 1% FS.

Technical data

Technology: Digmesa’s patented Laser-Flow measurement technology

Flow-Range: ~1-60ml/min

Accuracy: < 1% FS

Response time: ~50ms

Inner tube diameter: 4mm

Material measurement tube: borosilicate glass

Measurable liquids: adapted to most clear water- and alcohol-based fluids
