DESCRIPTION

This sensor sits in line with your water line and contains a pinwheel sensor to measure how much liquid has moved through it. There's an integrated magnetic hall effect sensor that outputs an electrical pulse with every revolution. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.

The sensor comes with three wires: red (5-24VDC power), black (ground) and yellow (Hall effect pulse output). By counting the pulses from the output of the sensor, you can easily calculate water flow. Each pulse is approximately 2.25 milliliters. Note this isn't a precision sensor, and the pulse rate does vary a bit depending on the flow rate, fluid pressure, and sensor orientation. It will need careful calibration if better than 10% precision is required. However, its great for basic measurement tasks!

We have an example Arduino sketch that can be used to quickly test the sensor, it will calculate the approximate flow of water in liters/hour.

The pulse signal is a simple square wave so it's quite easy to log and convert into litres per minute using the following formula.

Pulse frequency (Hz) / 7.5 = flow rate in L/min.

Shipping Policies:

  • To Ensure that your order reaches you in the fastest time and in good condition, we only ship our goods through SHIPROCKET, DTDC and SPEEDPOST.

  • We currently do not have an option for the customer to choose a delivery partner, Our logistics team will use the best possible shipping method to execute the order.
  • Our Team strives to ship all items in your order together but this might not be possible at all times due to the properties or availability of the products either case we inform the customer before proceeding with the shipment.

    Damage in Transit:

    1. If you find that the packing of package delivered is tampered or damaged and that it might have caused damage to the product inside before accepting the shipment, you must click a picture and refuse to accept the delivery and inform our Customer Care +91 8606650999 along with your order number. We will make our best efforts to ensure replacement delivery at the earliest.

    Order Tracking: You may track the order through the fulfilment emails send from our email: help@tomsonelectronics.com or through the SMS sent from SHIPROCKET to your registered mobile number at the time of placing order

    Shipping Time & Delivery:

    1. Orders Placed up to 4:00PM will be packed and prepared to be shipped on the same day.

    2. We make our best efforts to prepare the orders for shipping on the same day or within 24 hours from the time the order was received.

    3. Due to the pandemic the government has imposed a restriction on the functioning of delivery partners hence a slight delay can be expected in transferring the packages to the concerned delivery partners.

    4. Our logistics partners guarantee a delivery of packages within 1-6 Working days to anywhere in India there can be delays as each shipping partner has their own method and transit hubs to each location hence the exact delivery time is not predictable therefore we request all our customers plan your orders allowing sufficient time for the delivery.

    Making changes in order:

    For making changes in order, you can contact us via email or call within 2 hours from the time of placing order for making changes in following fields

    1. Product

    2. Quantity
