F SERIES INLINE FLOW METER

Precise monitoring of water consumption

High Accuracy
Ultrasonic flow meters offer precise measurements across various flow rates and fluids, ensuring reliable data even in challenging conditions.

Non-Invasive
With no need for insertion into the flow path, ultrasonic flow meters minimize pressure drop, eliminate leakage risks, and reduce maintenance, making them versatile for different applications.

Wide Rangeability
Ultrasonic flow meters accurately measure both low and high flow rates, making them suitable for diverse industrial and laboratory settings.

No Moving Parts
Without mechanical components, ultrasonic flow meters ensure long-term reliability and low maintenance costs, contributing to their durability and stability.

Accurate measurement of water usage is crucial for various reasons, playing a pivotal role in sustainable water resource management and conservation efforts. Precise monitoring of water consumption enables efficient identification of leaks, promotes responsible water use, and facilitates fair billing practices. Additionally, as global water scarcity becomes an increasing concern, accurate measurement becomes essential for informed decision-making and the development of effective water conservation strategies. Reliable water usage data is vital for businesses, utilities, and individuals to better understand consumption patterns, allocate resources effectively, and promote a more sustainable and equitable distribution of freshwater resources.

Ultrasonic technology offers numerous benefits over traditional measurement methods. Ultrasonic water meters utilize sound waves to measure the flow of water, eliminating the need for moving parts and minimizing wear and tear. This not only enhances the meter’s durability and longevity but also ensures accuracy over an extended period. The non-intrusive nature of ultrasonic sensors reduces the risk of clogging and maintenance issues, making them ideal for a wide range of applications. Furthermore, ultrasonic technology allows for real-time monitoring, enabling immediate detection of leaks or irregularities in water usage, contributing to rapid response and efficient water management.

Application of water meters is expanding and finding uses in diverse sectors. Beyond billing and conservation in residential areas, water meters are increasingly employed in industry, agriculture, and smart city initiatives. Industries benefit from accurate water usage data for process optimization, regulatory compliance, and sustainability reporting. In agriculture, precise water measurement aids in optimizing irrigation practices, conserving water resources, and maximizing crop yield. The integration of water meters into smart city infrastructure enables real-time monitoring and data driven decisions for efficient urban environments. As technology advances and awareness of water conservation grows, the versatility of water meters in diverse applications is likely to continue expanding.

SPECIFICATIONS

The F Series inline flow meters are engineered to elevate water treatment and usage measurement. Composed of stainless steel construction and no internal moving parts, these flow meters ensure durability and reliability even in the most demanding environments.

The F Series meter module operates as a pulse generating device with corresponding “K Factor” for accurate flow measurement when connected to commonly used industry controls.

*UPC recommends that water velocity within plumbed systems should not exceed 8 ft/sec.

DIMENSIONS AND IDENTIFICATION

ON POWER UP:
LED flashes indicator of power applied and sequence to show how dip switches are set for meter size.

1 Flash F311 1”
2 Flashes F314 1 ½”
3 Flashes F315 2”
4 Flashes F317 3”

DURING OPERATION:
LED flashes as forward flow is sensed within meter. Flashing is proportional to the rate of flow sensed.
IE: Higher flow rate produces higher frequency

APPLICATION GUIDE

Inline flow meters are most accurate when measuring fully developed, non-turbulent flow. The F-series meters have been calibrated for measuring liquids and may not read accurately if air or other gasses are in the pipe. Orient the meter to minimize entrapped gasses around the sensors.

These recommendations are meant to guide the installation and meter orientation to promote a full pipe condition. They are also meant to provide accessibility to the meter cap for viewing flow indicator and servicing.

The meter can be installed in horizontal or vertical orientations. The meter sensor module can be aligned at any angle in the plumbing.
The operation of the F Series meter requires that the “flow hoop” remain full without air bubbles at all times. Mounting the meter vertically with flow in the downward direction may not be advisable in some installations.

Do not run flow meter wiring in direct proximity to power line wiring. If connecting to one of the water treatment controls listed below, insert wires into the three-pin connector as shown. If connecting to another type of control, cut off the three-pin connector and strip wires as needed.

Observe the flow direction arrow on the meter body. For maximum accuracy, allow 10 pipe diameters of straight pipe before the meter and 5 pipe diameters after the meter. The straight pipe recommendation is to reduce turbulence in high flow velocity conditions. For example, if installing a 1.5” meter, there should be 15.0” (1.5” x 10 = 15.0”) of straight pipe before and 7.5” (1.5” x 5 = 7.5”) of straight pipe after the meter for the best accuracy.

Meter accuracy has been tested with units attached to outlet of control valves

A set of dip switches are provided on the circuit board to set the meter size. On flow meter assemblies these dip switches are preset at the factory and do not require adjustment.

When replacing a flow sensor module verify the dip switch setting as shown below:
