Remote Direct-reading Water Meter (Liquid Seal Type) vertical

Product Introduction

Liquid seal water meter characterized by:

  1. small starting flow (available for water conservation, 2L/H), capable of improving the recovery of water rate;

  2. high precision, long service life and accurate metering;

  3. less abrasion due to the soaking of counter gear in liquid;

  4. no “demagnetizing” hidden danger of dry water meter.

Dimension parameters

Performance parameters

Maximum permissible errors

  1. Maximum permissible error of water meter in the low area from the minimum low (incl.) to the boundary flow (excl.) shall be ±5%.

  2. Maximum permissible error of water meter in the high area from the boundary flow (incl.) to the overload flow (incl.) shall be ±2% (for cold water meter) or ±3% (hot water meter).

  3. Electro-mechanical transformation error: less than or equal to ±1 (minimum displayed scale division)
