Stainless Steel Pulse Output Water Meter - SPWM-100-CF. 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: 1" Stainless Steel Pulse Output Water Meter Mounting: Horizontal Inline Mount -- 1" Male NPT Pipe Threads Units: Cubic Feet Pulse Output: 1 pulse = approx. 0.748 gal. Approx. Dimensions: 14.5” long x 4" Wide x 5.5" tall Model: SPWM-100-CF
Our 1.0" Stainless Steel Pulse-Output Water Meters are a great way to monitor water usage, both locally or remotely.
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, or you connect the pulse output wires to a pulse counting device for remote readability. This meter produces a pulse for every 0.10ft³ (1 pulse = approx. 0.748 gal.) that flows by the meter, these pulses can be then picked up and counted by our pulse counting devices.
This meter has received California Type Approval from the California Department of Weights and Measures, which certifies that the meter's accuracy is revenue grade. This allows the meter's readings to be used for billing purposes.
This meter is not NSF 61 certified. For an NSF 61 certified model, please take a look at our SPWM-100-NSF.
Remote Water Reading:
This meter can tell you if you have a leak in your water system because it only takes ~6.0 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 water leaks can save a ton of money in water costs and overage fees, not to mention mitigating the damage that any leak can cause.
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:
You can use these water submeters to monitor the water consumption in your apartments, your irrigation water (which can save you in sewer costs in some areas), meter your well output, use them to detect leaks while you are away, etc.
Can the meter be set up to read GPM instead of cf?
This meter reads natively in cubic feet. In order to convert to gallons you would simply multiply the number of cubic feet by 7.48.
We need a simple 1.0" stainless steel water meter with cubic meter reading only we do not need a pulse output so in this regard can you quote for me for 2 pcs. and send it thru USPS.
This meter reads in cubic feet, not cubic meters. We do not carry water meters that read in cubic meters. The meter can be read directly on the dials like a traditional water meter. If you choose not to use the pulse output functionality it can be ignored or removed. Pricing for this meter is available above, in our online store which is where you can place your order. We ship orders via USPS by default unless you choose another option when you order.
Is this meter considered ultrasonic? How sensitive is the meter? Will it pick up a dripping pipe or hose bib?
This is a multi-jet meter, not an ultrasonic meter. The minimum rated flow rate for this meter is 1.77 ft³/hr. It will function below that rate but with less accuracy. So to answer your question, it really will depend on the drip rate the leak. Our HD 3/4" meters have remote read capability at .01ft³ resolution, so they are a good option for monitoring for leaks on 3/4" water lines, if you plan to read the meter via our Omnimeter Pulse v.4 and EKM Push system.
Can the water meter reading unit be in cubic meters instead of cubic feet?
This meter reads natively in cubic feet. You can convert the meter readings to cubic meters by multiplying them by 0.0283168. If you are reading the meter remotely with one of our software options then the software will do this conversion automatically if you set it up to do so.
Your meter has 3 wires. Connection instructions say \"pulse output wire to port 13 on omnimeter, ground wire to port 14\" Which is the pulse wire and which is the ground wire. Where does the 3rd wire go to?
The white wire is ground and should go into port 14 on the Omnimeter Pulse v.4. Either of the other two wires can be used for + into port 11, 12, or 13 on the Omnimeter Pulse v.4. The third wire is redundant and can be ignored.
In addition to the pulse rate, what is the accuracy? The description says "approximately" 0.748 gallons per pulse.
If you take a look at this meter's Spec Sheet you will find the error curve in section VII. This represents the accuracy of the meter and how it varies depending on the flow rate of the water passing through it. As you can see, the accuracy is typically +/-1.5%, except at low flow rates where it is more like +/-2%.
Can the meter resist some solids present in the water like little rocks or traces of soil?
Good question. It is not a good idea to have much if any discernable solids in your water. Paritcles of sand can abrade the inner workings of the water meter and can eventually cause either slowness in the water meter mechanism or other issues. So please try to limit this as much as possible. I would use either an inline sieve or a drop trap before the water meter or at least a tee before the water meter to help catch any particles that are coming down the pipe. I like to use a tee with about 6 inches of drop with a valve at the bottom for cleanout. I also like to install a check valve before the water meter, so that water can only flow in one direction through the water meter.
Can you help identify additional parts to allow your pulse meter to seen as a ModBus device by my BAS...?
Yes it is possible to get pulse data to your BAS system via a variety of methods:
1. Connect your water meter pulse output to an Omnimeter Pulse v.4, and use the BMS to read the Omnimeter over RS485 using the EKM protocol.
2. Connect your water meter pulse output to an Omnimeter Pulse v.4, and use the BMS to read the Omnimeter over RS485, but this time you would have us set the Omnimeter to a dual protocol modbus meter. Email us for details.
3. Connect your water meter pulse output to an Omnimeter Pulse v.4, and connect the Omnimeter to the EKM Push system, use your BMS to gather data from the cloud Open API (this is probably the easiest method).
Can you install the meter in a vertical position?
Hi, the 1" water meter cannot be installed vertically. It must be installed horizontally with the dials facing up. Depending on the installtion site it may be possible to plumb around the meter so that the piping goes horizontal to the meter and then turns up after the meter to go vertical, thus keeping the meter horizontal. We do carry vertical 3/4" meters but not in the 1" size.
