Meter Connection: Carlon supplies connections with all MRS meter orders.
Pressure rating: Do not exceed 150 psi.
PH Level Range: 6.5 - 8.0
Temperature Range: Protect the meter from freezing and within the temperatures of 35 to120 °F.
Accuracy: +/- 1.5% of maximum flow when operating between minimum and maximum flow range
Register Options: U.S. Gallons, cubic feet, metric.
The size of meter selected should be based upon continuous flow, GPM, as opposed to pipe size. For example,
if it is determined that continuous flow is 25 GPM, a 1“meter should be selected rather than a 3/4“ meter.
Installation Instructions:
1. Flush the line thoroughly after all plumbing changes to prevent contaminates from entering the meter.
2. Install horizontally with the register facing up and inlet port facing the water supply line.
3. Dry contact type, reed switch meters with maximum switching voltage of 48 V AC/DC, maximum
current .2 amps, 3 watts.
4. If an outdoor installation, meter must be protected from the elements.
Carlon warrants its products to be free of defect in material or workmanship for a period of
twelve months from the date of purchase. Contact us to obtain a copy of our complete statement of
warranty.
1. Install a Carlon Slow-Closing Valve downstream of your water meter.
This will eliminate possible meter damage from water hammer in your system.
2. Install a Carlon Strainer upstream of your water meter to protect the meter and any
other in-line process equipment from becoming jammed by particulate matter in your system.

Specify model number shown followed by choice of contact pulse settings desired.
Add a G for gallon reading or a C for cubic feet reading (call factory for other register reading abbreviations).
Example: 1 1/2" meter with gallon register and 10 gallons per contact = 150MRS-10 GPC.
