Woltman Water Meter With Positive Displacement and pulse emitter for irrigation hydrometer
   
  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:
   	- 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;
- 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;
- It can measure dirty water. The universality of the measuring mechanism is great.
- Negotiability ability is wide. Accuracy in measurement is exact.
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%.
