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:

Feature	Details
Flow variables measured	Mass flow, density, temperature; optional viscosity.
Sensor design	Straight single-tube design; “easy cleanable”.
Tube material / wetted parts	Titanium for measuring tube; other parts in stainless steel or coating depending on version.
Size range (nominal diameter)	DN 8 to DN 80 (≈ 3/8″ to 3″).
Accuracy	• Liquids: about ±0.1 % for mass & volume flow; <-- density accuracy in liquid ~ ±0.0005 g/cm³. • Gases: larger error, e.g. approx ±0.5 % mass flow.
Temperature / Pressure ranges	Medium temperature: from −50 °C up to approx +150 °C. Process pressure: up to PN100 (or equivalent), specifics depending on DN, material etc.
Environmental / Protection	High ingress protection (IP69K in many versions). Robust transmitter housing.
Installation	“Full-bore” design to minimize pressure drop. As its straight tube, less demanding for inlet/outlet runs compared to bent-tube designs.
Outputs / Communication	Multiple typical industrial outputs: analog (4-20 mA with HART), digital protocols (Modbus RS-485, PROFIBUS, PROFINET, etc.), pulse/frequency/switch outputs.
Additional features	Integrated web server for local configuration, diagnostics. “Heartbeat Technology” for verification and monitoring.

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.
