DAEAS200U-75P Water Meter with Pulse Output, 3/4" NPT Couplings, Measuring in Gallons

These meter are great! They are durable and accurate

I had to replace the same model I had. The good news is that it fit and was easy to replace the old one. The bad news is that I had to replace the old meter after about 5 years. It should be noted that the old meter was in an outdoor, high sun location and was made of plastic, so it may not have been the best choice for the location.

The price is great for what you get and so far I am very happy with the purchase. I know that DAE wants to make cash by selling a complete system but for home use it's not such a great deal. However I have been able to interface with an ESP8266 running ESPhome. So far it just works and I get to see my water use in real time and verify by taking a look at the meter directly plus I no longer have to go out to the curb and lift a cover to see what my water usage is on a daily/weekly/whatever else basis. And since this meter does have the ability to be certified if there is ever a discrepancy between my utility bill and what I show to have used I can use it to prove I have not used as much water as I am being charged for.For those interested in using ESPhome with this you will need a 10K pull up resistor installed on one leg of the wire lead for things to work properly then you simply short to ground for the count to work. The code I used for the sensor is included below and should work to get you up and running.- platform: pulse_counterpin:number: GPIO14inverted: truemode:input: truepullup: truename: "${disp_name} Flow"unit_of_measurement: "gal/min"icon: "mdi:water"update_interval: 15saccuracy_decimals: 0internal_filter: 400mscount_mode:rising_edge: DISABLEfalling_edge: INCREMENTfilters:- lambda: return (x);total:name: "Total Water Consumption"unit_of_measurement: "gal"device_class: waterstate_class: total_increasingaccuracy_decimals: 0icon: "mdi:faucet"

I have purchased both a cold water and hot water version of this pulse meter. I am happy with both but there is a caveat. The meters do not come with a back-flow preventer. This is essential otherwise as water sloshes back and forth through this meter due to pressure changes it will continue to generate pulses even when there is no net flow.The difficulty is easily avoided by installing their $5 back flow preventer that can be purchased on Amazon. It would be nice if they would make this clear in their web material for the pulse meter.https://www.amazon.com/DAE-NRVAS-75-Non-Return-Valve-AS200U-75P-AS200U-75RP/dp/B0C582TKQ1/ref=sr_1_1?crid=1FN9UOIKMR2L1&keywords=dae+nrvas-75&qid=1687010393&sprefix=dae+nrvas-75%2Caps%2C126&sr=8-1Of course other kinds of check valves in the line would also solve this problem.I found Tech Support at DAE to be very responsive and helpful.

The DAE AS200U-75P has proven to be an invaluable tool for monitoring and determining the optimal time to change my whole house water filter. With its user-friendly interface and reliable performance, this device simplifies the process of tracking the condition of the filter. By providing accurate measurements and clear indications, it helps me ensure that my water filtration system is operating at its best and that I'm getting clean and safe water throughout my home. Since it is my first set of filters, I have to see what happens at around 10K gallons of water. I can better gauge on when my next change should be.

Was able to run it with esphome by using a wemos d1 mini, just attach one cable to ground pin and ine to d5(gpio14), no resistor needed, code does that internally for you. Home assistant sees it right away and runs like a charm with this code:sensor:- platform: pulse_counterpin:number: GPIO14inverted: truemode:input: truepullup: truename: "${upper_devicename} Flow"unit_of_measurement: "gal/min"icon: "mdi:water"update_interval: 15saccuracy_decimals: 0internal_filter: 400mscount_mode:rising_edge: DISABLEfalling_edge: INCREMENTfilters:- lambda: return (x);total:name: "Total Water Consumption"unit_of_measurement: "gal"device_class: waterstate_class: total_increasingaccuracy_decimals: 0icon: "mdi:faucet"

Wanted to count US Gallons used in the house without having to go outside and read the underground City meter.My town charges for over consumption. I've been monitoring for 13 years... at the outdoor meter.This does the trick. So simple to install. No real need for the very expensive iPhone capability unless it is important to you. If you wish, the new unit displays to a remote counter through a small 2 conductor wire to wherever you like. It displays ACCURATELY how many gallons have passed through the water meter. The Amazon DAE CO-10 Electronic Pulse Counter or any other Pulse counter will work with this. I already had a tiny EKM Metering remote. It registers the gallons perfectly Really, you do not need to use the remote function. The display at the meter is clear and easy to read. No external power required. Just follow instructions that warn that the unit MUST be installed horizontally with the face up.Thank You DAE for such an amazing meter at a great price.

I use this for my job. This was my third unit and I only get about a year and a half out of each when one day they just don't register a drop. This last one just died today. I'll be searching for something different.
