Woltman heat water meter for heat supply utility billing, Size DN100, PN16
Heat water meter, also can serve as heat meter. This type of water meter also can be used for a remote reading transmission system as equipped with a built-in sensor.
APPLICATION: To totalize the total volume of cold (hot) water passing through the pipeline.
WORKING CONDITION:
- The max.admissible water pressure: 1.0MPa OR 1.6MPa.
- Water temperature: 0.1℃~50℃ for cold water ; 0.1℃~90℃ for hot water.
FEATURES:
- Measuring mechanism has three different types.
- Removable element structure, it is easy for installation and maintenance, register for universal use within this range detachable without Removing the meter from the pipeline;
- Dry-dial, Magnetic drive sensitive action, small pressure loss;
- Counter of roller-big central pointer type, easy reading;
- Vacuum sealed register ensures the dial keeps free from fog and keeps the reading clear in a long term service;
- Selected high quality materials for steady & reliable characteristic;
MAXIMUM PERMISSIBLE ERROR: - From transitional flow up to maximum flow both inclusive:
±2% for cold water.
±3% for hot water. - From minimum flow inclusive up to transitional flow: ±5%.
