Intrinsically Safe Logging Gas Flowmeter - Protea Model PF100

For Flow Monitoring * Stack Testing * Process Investigation * Vent Troubleshooting

PF100

Gas Flowmeter Probe and Control Unit

Protea's logging flow meter has a large measuring range and the ability to detect very low flows. The measuring sensor and signal cable are intrinsically safe and robust, intended for critical and difficult measurements such as chemical plant vents and stack testing applications.

The sensor uses thermal mass technology to measure flow rates from under 0.1m/s to 40 m/s in pipe sizes upwards of 50mm diameter. The meter is programmable for gas composition and pipe diameter. It directly displays the velocity of gases flowing in a pipe.

All readings are displayed on the control box, and if used with the flow logging option, can be viewed as real time velocity profiles. The data can be easily downloaded and transferred into other programs such as spreadsheets.

FEATURES AND BENEFITS OF THE PF100:

Features	User Benefits
Intrinsically Safe	The probe and communication cable system are certified as intrinsically safe.
Variable Pipe Diameter	The probe can record flows in pipe varying in diameter from 75mm upwards. An option is available to extend measurement down to 50mm pipe diameter.
Direct Reading flow	Directly displays in normalized m/s.
Wide velocity range	Equivalent velocity range is from 0.1 m/s to over 40 m/s.
Accuracy	Accuracy of the probe is +/- 0.5% of full scale, or within 2% of reading.
Repeatability	Repeatable to within a standard deviation of 0.25%.
Fast response time	Response is instantaneous, with logging frequency down to 1 second.
Wide temperature Range	Permissible process temperature from -10 to +110ºC.
Flexibility of use	The sensor can be placed up to 100m away from the control unit.
Automated operation	The PF100 can be used by minimally-skilled operators.
Rugged design	The PF100 can be supplied with a rugged case for longer life.

PF100 has three parts:


Rugged stainless steel Probe (IS)	Communications cable up to 100m (IS)	Control unit (non-IS)

CONTROL UNIT SPECIFICATIONS:

Dimensions (mm) are 135(h) x 261(w) x 300(d)
Requires a 110v/240v power supply
Unit should be located in a 'safe area' up to 100m from the intrinsically safe sensor
Logging software is also provided, to log velocity readings and also provide velocity profiles
