Pulse Water Meter with WiFi Wireless Option
The MJ20S meter emits a pulse for each gallon of flow and can register as little as 1/4 a gallon. This greatly helps in determining leaks given our gallons over time alert feature (settings within free online dashboard).
Included for free with the meter are 3/4" Polymer Meter Couplings.
Features: 4.5" Short Version of the popular MJ20 model water meter. Polymer (Glass-reinforced Nylon) body with brass threads. Dry Contact Reed Switch Pulse Output. Sealed register for tamper resistance and quiet operation NSF 61/g listed and marked. Meets AWWA C708 accuracy performance. 1-year new meter accuracy warranty. 5-year standard warranty for body, register, and accuracy. Specifications: Product Dimensions: 4.5 x 3.5 x 3.9 inches Shipping Weight: 1 pound 15 gpm continuous, 20 gpm max. 105 F max temp. 150 psi max.
Description: The MTW MJ20/MJ420 multi-jet water meter uses a polymer body design to allow for low weight and reduced cost but augments the meter with brass threads to reduce the likelihood of stripped threads during installation. The metal threads to not come into contact with the water thus allowing the MJ20/MJ420 to meet NSF61 standards as well as the Annex G 0.25% lead requirement also known as NSF372. The MTW MJ20/MJ420 may be installed either horizontally or vertically.
Please see our WiFi pulse meter monitoring system add-on feature. It allows one to monitor the water use over the internet via a forever free online dashboard and cloud service. The user can view the gallons over time via two charts, set text and or email alarms and download the data to an excel format file.
