Application: --Measuring the total volume of cold portable water passing through the pipeline. Construction --The meter consists of a body, a measuring unit, a register unit, a retaining ring and other parts. The retaining ring secures the internal parts. Working Principle: --This is a multi-jet impeller meter with a drive magnet and a internal dry type register. The impeller movements is transferred by a magnetic coupling to the vacuuming and hermetically copper sealed register, which the reading is made. Compliance with Standard: --Technical data confirms to ISO 4064 Class B Standard for horizontal installation. Attachment: --With every water meter(threaded ends), there are 2 couplings, 2 coupling nuts, 2 coupling gaskets and 2spud thread protectors Indication: --Cubic meter(m3) for selecting. Feature: --Multi-jet, dry-dial, easy for maintenance, with external regulating device; --Magnetic drive reliable characteristic, long working life, magnetic shield used for external magnetic fieldprotection; --Vacuum sealed register in copper sealed chamber ensures the dial keep free from fog and frost, Keep the reading clear in a long term service; --Inlet strainer, non-return valve for selection; -- Technical data conform to international standard ISO4064 Class B Working condition: Water temperature: 0-50C for cold watermeter . Water pressure : ≤1.6Mpa Maximum permissible error: (1) in the lower zone from qmin inclusive up to but excluding qt is ±5%. (2) in the upper zone from qt inclusive up to and including qs is ±2%;
