Overview

Description

The FS1025-DL comprise a MEMS flow sensor mounted on a circuit board with an amplification circuit and a flow housing.

The FS1025-DL is targeted for liquid applications. The sensor utilizes thermopile sensing, which provides an excellent signal-to-noise ratio and is ideal for applications requiring low power. It is highly sensitive at low flow rates with a very fast response time.The FS1025-DL outputs a non-linear curve with flow. It features an Analog, 0 to 4.5V, and Digital I2C output.

FS1025-DL complies with NSF/ANSI 61: Drinking Water Systems Components - Health Effects. It can be safely used in water and beverage applications.

Features

  • Measures liquid mediums

  1. Waterproofing a FS1025-DL water flow sensor.

    Hello All, I am in need of a sensor to measure water flow but it may be partially submerged. I think the FS1025-DL would be perfect for the application except for the lack of waterproofing. I would like to know the feasibility of opening the case and using protecting ...

  3. FS1025-DL less sensitive and then stopped reporting flow

    Hello, I have been testing out the FS1025-DL and it was working very well in our seawater system.  But it appears to have failed, a few weeks ago the flow started drifting lower and now it reads zero, after taking it apart it appears that there is some corrosion ...

  1. FS1025 - Sensor die on FS1025-DL and FS1025-DG

    Yes.  The difference between the two is based on calibration procedure (gas has a full calibration sweep).  Liquids were decided to have a 2 point calibration only for production efficiency.

  2. FS1025 - Calibration on FS1025-DL

    The FS1025-DL is NOT a fully calibrated module over the entire span of the flow range. It features a trimmed span from zero flow to full scale, 0 to 7 liters/min. We trim these two flow points to be the same for each module. The curve for ...
