Description
- Poly casing with brass threads
- Available in cold (MJ20S) and hot (MJ420S) versions
- Pulse output (1/10 gal) or (1/1 gal)
- Sealed register for tamper resistance
- Meets AWWA C708 performance
- NSF/ANSI 61 and 372 listed and marked
- Quiet operation
For use in submetering applications where compact size and pulse output are desired. The MTW MJ20S/MJ420S multi-jet water meter uses a polymer casing 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 MJ20S/MJ420S meet NSF/ ANSI 61 and 372 standards. The MTW MJ20S/MJ420S may be installed either horizontally or vertically. We suggest using fiber washers with the MJ420S.
The MJ20 Cold Short and MJ420 Hot Short poly meters are specific variants of water meters designed for particular applications and space constraints. Here’s an overview of each:
- MJ20 Cold Short Poly Meter:
- Application: The MJ20 Cold Short Poly Meter is designed for measuring the flow of cold water in situations where space constraints necessitate a shorter meter body.
- Polymer Housing: Similar to other poly meters, the MJ20 Cold Short features a durable housing constructed from high-quality polymer materials. These materials offer corrosion resistance and durability while maintaining a compact size.
- Temperature Range: It is suitable for use with cold water at ambient or low temperatures, typically ranging from near-freezing to room temperature.
- Accuracy and Reliability: The MJ20 Cold Short meter is engineered to provide accurate measurement of cold water flow rates, ensuring reliable performance despite its compact design.
- Installation: Due to its shorter length, the MJ20 Cold Short meter may be easier to install in locations where space is limited. It is installed in-line within the plumbing system and is compatible with standard plumbing fittings and connections.
- MJ420 Hot Short Poly Meter:
- Application: The MJ420 Hot Short Poly Meter is specifically designed for measuring the flow of hot water in situations where space constraints necessitate a shorter meter body.
- Polymer Housing: Similar to the MJ20 Cold Short, the MJ420 Hot Short meter features a durable polymer housing designed to withstand the higher temperatures associated with hot water usage while maintaining a compact size.
- Temperature Range: It is suitable for use with hot water at elevated temperatures, typically ranging from above room temperature to near boiling.
- Accuracy and Reliability: The MJ420 Hot Short meter is engineered to provide accurate measurement of hot water flow rates, ensuring reliable performance even in compact installations.
- Installation: Like the MJ20 Cold Short, the MJ420 Hot Short meter is designed for easy installation in locations where space is limited. It is installed in-line within the plumbing system and is compatible with standard plumbing fittings and connections.
Both the MJ20 Cold Short and MJ420 Hot Short poly meters offer compact, space-saving solutions for water metering in their respective temperature ranges. Despite their shorter length, they maintain the accuracy, reliability, and durability expected from water meters, making them suitable for a variety of applications where space is at a premium.
