MODEL: WI-50E-300E WIY -50E-300E The WI irrigation water meter has been designed for irrigation and other applications where standard woltman type meters cannot be used because the water contains large solids. WI meters feature an especially large water passageway that is intended to allow large solids to pass through the meter.
Although designed with irrigation use specifically in mind these meters also find use in process applications where waste water contains a high solid content such as in some food processing plants. The availability of versions with an electrical output allows the use of remote display and monitoring equipment.
Features and Benefits
• Paddle wheel design resists blockage and damage to meter from solids in water.
• High tolerance to water containing solids due to the open design.
• Negligible loss of head.
• Wide flow range accuracy.
• Suitable for irrigation and waste water applications.
• Evacuated and sealed dry dial counter ensures clear reading.
• Field replaceable insert, one insert covers full range of sizes.
• Magnetic coupling between paddle wheel and counter.
• Bearings are constantly flushed during operation to eliminate deposit of solids.
• Pulse output models available (WIY series)
• Suitable for installation in any orientation
• Steel cover with padlock facility to protect the counter.
• Flanges can be drilled for BS, ISO or ASA flanges.
APPLICATION
◆Measuring the volume of cold (hot) water passing through the pipeline.
◆This type of water meter can be used for a remote reading transmission system as equipped with a built-in sensor.
WORKING CONDITION
◆Water temperature: 0.1℃～50℃ (0.1℃～90℃ for hot water meter)
◆Water pressure: ≤1.0Mpa (1.6MPa on request)
MAXIMUM PERMISSIBLE ERROR
◆In the lower zone from qmin inclusive up to but excluding qt is ±5%
◆In the upper zone from qt inclusive up to and including qs is ±2% (±3% for hot water meter)
