What is the Promass I 100

The Promass I 100 is a high-performance Coriolis mass flowmeter designed for industrial applications, offering measurements of mass flow, density, and temperature, with optional viscosity measurement.

It is part of the Endress+Hauser “Promass I” line, featuring a straight single-tube sensor design and very compact transmitter housing.

Measuring principle

• The fundamental principle is Coriolis force measurement: the flow tube is vibrated and the fluid flowing through causes a phase shift in oscillations between inlet & outlet positions. This phase shift is proportional to mass flow.
• The tube is excited at its resonance; changes in oscillation frequency due to changes in mass (tube + fluid) are used to compute density.
• Temperature of the measuring tube is also measured, both for fluid temperature and to compensate temperature effects.

Key Technical Features & Specifications

Here are some of its important characteristics:

Advantages

• High accuracy and stability: Since the measurement is mass‐based and not strongly influenced by fluid viscosity, density, or flow profile, it gives very reliable readings.
• Multi-variable measurement: Flow, density, temperature (and viscosity optionally) reduce need for multiple sensors.
• Compact & robust: Small footprint transmitter, full-bore, straight tube helps in installations where space is limited and/or cleaning is needed.
• Low pressure loss: Full bore and straight single tube help minimizing pressure drop. Good for sensitive fluids.
• Good for hygiene and cleaning: Because of the easy-clean straight tube. Also options exist for hygienic/stainless housing.

Limitations / Considerations

• Cost tends to be relatively high vs simpler flowmeters. More sophisticated construction, more electronics.
• For very low flow or very small diameters, sensitivity and signal-to-noise becomes more challenging ‒ need to check minimum flow (cut-off) for your application.
• The wetted materials (Titanium, stainless) have to be compatible with the fluid (chemically, abrasive, etc.). If the fluid is aggressive or contains solids, consider wear or corrosion.
• Temperature and pressure limits: depending on the exact model; ensure your process operating envelope fits within them.
• Maintenance might require more care (cleaning, calibration) due to the precision of the instrument.

Typical Applications

The Promass I 100 is suitable for many industrial sectors, especially where accurate mass flow + density + temperature are needed, such as:

• Chemical process lines
• Food & beverage where hygiene / cleaning is required
• Pharmaceuticals
• Oil & gas (for certain liquids/gases)
• Skid / module builders (because of compact size)
• Any application where pressure drop must be minimized or full-bore is preferable.
