Pulse to Voltage Translator Details
Our pulse to voltage translator allows you to easily connect flow sensors to any data logger. This saves you money, because you can use low cost loggers, that don't have pulse inputs.
The translator has an internal pull up resistor on its input line, and will accept pulses from all sensors that have pulsed open drain/collector outputs.
We've made it easy to verify your flow sensor is working. The LED pulses whenever it receives 20 input pulses for quick visible verification.
Optimized for Linearity and Resolution
The translator will convert pulse rates from 0 to 1000Hz linearly to a voltage range of 0 to 3V. There are 4 pulse frequency ranges that can be selected with an internal jumper:
- 0 to 125Hz.
- 0 to 250Hz.
- 0 to 500Hz.
- 0 to 1000Hz.
Vegetronix Modular Building Blocks
We take a modular approach with our product lines. Each product is simple and low cost, and will easily interface to all of our other products. This approach allows you to build any type of application from our basic set of components.
Get Emails and Text Alerts
When used with our WiFi Sensor Hub you can get email or text notifications of leaks, or unexpected water usage as indicated by your flow sensors.
Optional Easy to Mount Enclosure
To keep the cost low, we sell the board by itself, or you can optionally pair it with an enclosure. The enclosure is made of 3D printed PLA. The top part is of the case is transparent, enabling you to see the internal LED. The bottom part has flanges with mounting holes, making it easy to mount.
You can purchase the case from us for minimal cost, or 3D print your own enclosure, by downloading the VG-PULSE-TRANS-CASE STL files and printing the case yourself.
Need a 4-20mA Current Loop Output?
Drawing under 1mA it can easily be paired with our current loop translator, which transforms any voltage output device into a current loop output device. Because it draws under 4 mA, it can be loop powered. If your flow rate sensor brings the total current draw above 4mA you can still use the current loop translator, but you will need to power it from an external source, rather than the current loop.

Pulse to Voltage Translator - Configuration
To configure the translator you will need to figure out the maximum
pulse rate of your flow sensor in Hz.
Set the range jumper to the closest setting that is higher than this value.
The sensor's data sheet should tell you the maximum pulse rate.
Most sensors have specify the pulse rate as a factor of flow in the following form:
where Q is the flow rate, normally in liters/min,
and K is a scaling factor.
For example if your sensor has a maximum flow rate of 30 liters/min, and a scaling factor of 11. Then your maximum pulse rate would be 330Hz (30*11), and you would use the range setting specified by 500Hz, as this is the next highest value above 330Hz.
