Electric Piezometers


Electric Piezometers are used for monitoring and measuring water pore pressure in various geological and construction applications, including:

  • Monitoring water pore pressure in rocks and soils.
  • Measuring pore pressure variation in selected locations in rock and soil.
  • Measuring water drain and uplift hydraulic pressure.
  • Measuring water drain from waste disposal sites.
  • Measuring pore pressure in retaining walls, piles, culverts, tunnel linings, etc.
Typical specifications for models BRMS-PZBR and PZCR:
  • Measuring range: Customizable based on client requirements.
  • Measuring resolution: Typically ±0.025% of the measuring range.
  • Measuring accuracy: Typically ±0.5% of the measuring range.
  • Calibration factor: 1.00.
  • Temperature effect: Less than ±0.05% of the measuring range per degree Celsius.
  • Probe material: Stainless steel.
  • Filter material: Ceramic/bronze filters (high/low air entry, as required).
  • Filter permeability: Determined based on high/low air entry type.
  • Filter length: Typically 100 cm (adjustable to client’s specification).
  • Filter diameter: Typically 20-25 mm (adjustable to client’s specification).
Main Distinguished Features:
  • Negligible temperature effect on measurement accuracy, ensuring reliable data.
  • Quick response to changes in pore pressure, allowing for timely monitoring.
  • Capability to be equipped with an automatic readout system for convenience and efficiency.
Available Models:

Electric Piezometers are available in two main types:

  1. High air entry type.
  2. Low air entry type.
