ZHA KL Series

Product catalog summary
Overview
The ZHA KL Series Gear Flow Meters are designed for measuring flow in lubrication and non-lubrication liquids, suitable for filled, viscous, and abrasive media. Made from high-strength aluminum and equipped with precision ball bearings, these meters ensure high measurement accuracy and durability. They are ideal for applications such as metering, monitoring, mixing, and dosing.

Specifications
- Measuring Accuracy: Up to ±0.1%
- Repeatability: ±0.05%
- Pressure Resistance: Up to 420 bar (6,000 psi)
- Temperature Range: -40°C to +150°C (-40°F to +302°F)
- Materials: Aluminum housing, stainless steel ball bearings, FKM/PTFE seals

Design and Principle
The gear flow meters operate on a positive displacement principle with two gears rotating inside a chamber. The rotation frequency, proportional to the flow rate, is measured by sensors. The meters are calibrated in-house, considering the customer's specified operating viscosity.

Applications
- Hydraulic applications
- Cylinder monitoring
- Fuel measurement
- Coolant circuit monitoring
- Dosing systems
- Lubrication monitoring

Features
- High measuring accuracy and repeatability
- Short response times
- Robust construction for long service life

Technical Data
Various models (ZHA 01/2, ZHA 02, ZHA 03, ZHA 04) offer different measuring ranges and K-factors, with pressure resistance up to 420 bar and frequency ranges suitable for diverse applications.

Calibration
Calibration is performed using high-precision systems, ensuring traceability to national standards. The calibration factor (K-factor) is determined for each meter, providing accuracy across the measuring range.

ZHA KL Series-3

ZHA KL Series – Gear Flow Meters The ZHA KL gear flow meter series (aluminum design) are flow meters which are mainly used in lubrication and non-lubrication liquids. They are equally suitable for filled, viscous and abrasive media. Only high-strength aluminum is used in manufacturing the gear flow meters. Combined with the use of high quality precision ball bearings, the ZHA KL guarantees optimum measurement accuracy and a long service life even under the toughest application conditions. The ball bearings facilitate a very low starting torque of the measuring element. This way even the lowest...
