3/4" Stainless Steel High Definition Pulse Output Hot Water Meter - HOT-SPWM-075-HD. This is a great stainless steel water meter that can be read locally, or can be set up to be read remotely when paired with an Omnimeter Pulse v.4 and an EKM Push gateway.
The complete system provides your water meter data in the cloud for free! No recurring fees of any kind.
Type: 3/4" Stainless Steel, High Definition Pulse Output, Hot Water Meter
Mounting: Horizontal Inline Mount -- 3/4" Male NPT Pipe Threads
Our remote readable 3/4" Stainless Steel Pulse Output Hot Water Meters are a great solution for remotely, or locally, monitoring hot water consumption. This meter is capable of metering water from 32ºF–194ºF.
This is a well made, industrial grade, stainless steel (304 grade) water meter. You can use it as a traditional water meter where you read the water consumption off of the face of the meter. It also has the added functionality of being able to connect the pulse output wires to a pulse counting device. This meter produces a pulse for every 0.01 cubic foot (approx. 0.075 gallon, or 0.283 liters) that flows by the meter, these pulses can then be counted by one of our pulse counting devices.
This meter is designed to generate pulses at a high rate to provide high granularity data when set up to read with a computer. This high granularity can provide better insights into usage patterns. In particular, it can tell you if you have a leak in your water system, because it only takes ~0.6 pints of water leakage to generate a pulse. In other words, if you see a pattern of pulses when you shouldn't (when you aren't intentionally using water) then you probably have a leak somewhere. The number of pulses over a given period of time will tell you how severe the leak is. Identifying and fixing hot water leaks can save a ton of money in water heating costs, not to mention mitigating the damage that any leak can cause.
Remote Water Reading:
This pulse output water meter can be connected to our EKM-Omnimeter Pulse v.4, which is our new pulse input meter. This is our most advanced electric meter to date. This meter can count the pulse outputs from up to 3 pulse output devices. It can also control up to 2 external relays, which allows you to turn things on and off remotely.
This water meter, when connected to a v.4 Omnimeter, can send pulse data to the cloud with our EKM Push communication system. The EKM Push sends all of your meter data to our cloud database and inserts it into your personal account, where you can access it for free. In other words, with this system you can easily monitor water use, at an unlimited number of sites around the world, for free.
Encompass.io is our free online meter management platform for monitoring data, managing meters, generating bills, and more. It is designed specifically for people who are remotely reading their meters via the EKM Push system. This platform can be used to visualize data on customizable dashboards, visualize cost, monitor trends, group meters, and a lot more. Each meter and meter group in Encompass can also be set up to email you, and/or your tenant, PDF bills. Here is a sample PDF water bill:
The EKM Widget offers another option for quickly seeing your water meter data online. It is also easy to save and share your Widget setting once you have it setup how you want. Here is an example:
Use these water submeters to meter the water consumption in your apartments, your irrigation water (which can save you in sewer costs in some areas), meter your well output, or use them to detect leaks while you are away.

This meter is not NSF 61 certified.
Note: To prevent condensation from building up inside the clear plastic dial cover, we recommend that you insulate the meter really well. In particular, insulate the meter dials really well. This can be done by wrapping the meter in a towel or some other form of insulation. The idea is to keep the air inside and outside of the meter at the same temperature, which prevents condensation from forming.

What is the minimum flow rate that can be detected?
The minimum flow rate is 1.77 cu. ft/hr (this is 13.24 gallons per hour). This is the lowest flow where the meter maintains accuracy. As for "the minimum flow rate that can be detected": this water meter model will still continue to turn at lower flows than this, I have seen 3/4" water meters turn with about 3-5 drips per second going through them. Please see the spec sheet for this meter for more information: http://documents.ekmmetering.com/EKM-HOT-SPWM-075-water-meter-spec-sheet.pdf
How tamper resistant are they
All of our water meters are very tamper resistant and tamper evident. They come with their own meter seals installed. You can add your own meter seals. The meter seals prevent someone from being able to access the internals of the water meter. You can use a meter seal on the coupling nuts of 3/4" HD water meters. Each water meter comes with its own serial number. Our 3/4" and 1.0" Water Meters have been tested to be revenue grade accurate by the California Department of Weights and Measures, part of this testing is that they be tamper proof or tamper evident.
