Prime Probe

Bi-directional, insertion, full bore, electromagnetic flowmeter for permanent or portable use.

RUGGED INSERTION FLOWMETER

FLEXIBLE | DURABLE | COST-EFFICIENT

The PrimeProbe is a cost effective alternative to full-bore flow meters and is ideal for use over a wide range of flows and pipe diameters. The flexible data logging capacity enables sophisticated convenient data analysis, delayed or in real-time.
Features & Benefits At A Glance

Ability to measure flow on all common pipes

Battery life of up to 10 years

Rugged - can operate at up to 25 bar

Remotely connects to Cloud Analytics software or SCADA systems

SMART mode optimum performance

PrimeProbe SMART mode offers optimum accuracy whilst preserving battery life. This mode automatically adjusts the measurement response time when variation of the flow velocity occurs. This gives more accurate results when the flowrate is changing rapidly and also preserves battery life when the flow-rate is stable.

Operation

Installation in pipelines is typically via a small valve tapping. It may be installed with the sensor on the pipe centreline or at the position of mean velocity (1/8 pipe diameter). PrimeProbe is a very rugged device with a strong stem and sensor, plus a safety chain. It is available with a choice of six insertion lengths and is waterproof to IP68.

Flexible data collection

The PrimeProbe provides a pulsed output which may be connected to a PrimeLog+ data logger (for local data collection) or to XiLog+ (for remote data collection). XiLog+ data can be transferred to any FTP server to be viewed online using PrimeWeb or connection to SCADA systems.

Logged flow and pressure data can also be transferred to PrimeWorks or XAP Desktop, providing graphing, reporting, export and database facilities.

Flow Profiling

If the flow velocity profile is fully developed, the flow meter provides an accurate measurement of water velocity and flow volume. A software package is available to determine the velocity profile by measuring at multiple positions across the pipe.

Measurement range

Bi-directional from 0.02m/s to 5m/sec (maximum may be lower dependent upon insertion length and position in pipe)

Accuracy

Point velocity ≥0.4m/s; ±2%

(See Note 1 below)
