Overview

The HFM900 is a flanged liquid turbine flow meter for measuring volumetric flow in a closed, full pipeline. The DN50, DN80, DN100 and DN150 versions cover normal flow ranges from 4 to 300 m³/h, depending on nominal diameter.

Fluid passing through the meter rotates an internal turbine. A magnetic pickup detects the rotating blades and generates a pulse frequency proportional to instantaneous flow. The signal can be sent to a compatible display, totalizer, PLC or control instrument for flow indication and totalization.

Available configurations include pulse output, 4–20 mA output, an LCD with battery supply, or an LCD with 4–20 mA and 24 VDC supply. RS485 and HART can be configured for project orders. The selected diameter, flow range, pressure rating, output, display and flange standard must be confirmed before ordering.

HFM900 is intended for clean, low-viscosity liquids that do not corrode the selected wetted materials. It is not designed as a general-purpose meter for slurry, fibrous liquid, gas or steam.

Features

Cemented carbide bearing thrust type,
Better accuracy, wear resistance
Simple structure, firm
Convenient disassembly and assembly.

Industrial Applications

The HFM900 flanged liquid turbine flow meter can be configured for suitable clean-liquid applications including:

Filtered process-water measurement
Water-supply and distribution equipment
Clean petroleum products and compatible light oils
Compatible low-viscosity chemical liquids
Metallurgical cooling and utility circuits
Paper-making clean-water and additive systems
Filling, batching and process-skid monitoring
Plant energy and liquid-consumption monitoring

The meter measures volumetric liquid flow. It is not intended to measure gas, steam, slurry or fibrous liquid.

Suitability for flammable liquids depends on the exact fluid, installation, output configuration and hazardous-area approval of the supplied unit.

An explosion-protected configuration is available as an ordering option. Before hazardous-area use, confirm the marking, certificate, gas group, temperature class, electrical connection and installation requirements for the exact unit.

A standard HFM900 must not be treated as explosion protected solely because an optional version exists.

FAQs

Can reducers be used to install the HFM900 in a larger pipeline?

Reducers can be considered, but the meter must be sized from the actual flow range rather than the main pipe diameter alone.

Use gradual, concentric transitions where appropriate and provide enough straight pipe to restore a stable velocity profile before the meter.

Can one K-factor be used for several HFM900 meters of the same size?

No. Each turbine sensor has its own calibrated meter factor. Enter the K-factor supplied with that individual meter into the display, counter or PLC.

Using an average value or another meter’s factor can affect both flow rate and accumulated volume.

Can the HFM900 control a batching process directly?

The sensor provides a flow signal. Batching requires a compatible totalizer or controller, logic settings and a correctly sized control valve.

The complete system must account for valve closing time and residual liquid movement after the stop command.

What are common signs of turbine bearing wear?

Possible signs include delayed rotor startup at low flow, lower-than-expected readings, reduced repeatability or a change in the meter factor.

Inspect the rotor and bearings and verify the meter against a reference before adjusting the receiving instrument.

Why can the indicated flow fluctuate when pump speed is stable?

Possible causes include entrained gas, cavitation, pulsating flow, an incompletely filled pipe, disturbed inlet flow, rotor contamination or electrical interference.

Check the hydraulic installation and pulse signal before changing calibration settings.
