FL101 In-Line Ultrasonic Flow Meter
Product Information
FL101 is specially used to measuring the flow of various liquids in
pipelines, realizing real-time flow measurement in the production
process. The instruments outputs digital signals, analog signals,
etc., so as to realize the measurement and control of the
production process.
Due to the need of industrial upgrading, instruments are required
to have rich outputs to achieve automation. However, the output of
traditional flow meters is relatively simple and cannot meet
on-site needs, and it need to be replaced in the original position.
Flo-Instruments has launched a in-line flow meter with a full
straight pipe design without pressure loss, double union
connection, and simple installation.
Benefits

- Clear at a glance, Low light, dim environment, Easy to read
|
 |
- Innovative menu method (drop-down list)
- Four-touch buttons for easy setup
- Simplified/Traditional/English language switching
| - IP66
- Injection molding structure
- Double union connection, easy and reliable

Compatible Medium
Since the product was put on the market, it has been widely used in
the cleaning equipment industry. Due to its simple installation and
operation, and reliable measurement performance, it has been
continuously promoted in new industries.
Main industries: semiconductors, food, medicine, drinking water,
detergents, printing and dyeing, chemical products, etc.
 | The medium users have measured:- Dilute sulfuric acid
- Liquor
- Hydrocarbon
- Alcohol
- Sodium chloride
- Sodium carbonate
- Triethylamine
- Ethylenediamine
- Propylene oxide etc
|
As the market expands, we will find that there will be more and
more media to be measured. We hope that users will share more
applications so that we can continuously enrich and improve our
products.
Determination of measurable media:- The flow rate of the medium in the pipeline is stable
- The pressure is maintained at 0.3MPa
- No bubbles (cavitation) will be generated due to flow
There are many more media that have been measured, welcome to
consult. |  |
