Market: Water Supply

Application Category: Monitoring

GPI Flow Meters Used: G2P05N09GMA

Problem:

Opening the pipe to measure sample flow rate could expose technicians to toxic levels of ozone. Leaving valves wide open wastes large volumes of water. If the flowrate is to low or too high analyzer readings are not accurate.

Flow Meter Application:

At the end of the ozone chambers, there are instruments for measuring residual levels of ozone. These ozone analyzers require 1-5 GPM. The sample line runs to a closed waste line, in case there is a high level of ozone. Safety to technicians is a concern when working with ozone. Leaving valves wide open wastes too much water. Flowrate cannot be too low or too high and still expect accuracy in the analyzer reader. Rotameters had been used but failed due to turbidity levels and the float would stick.

Flow Meter Drawing:

Solution:

G Series Meters added to the individual lines send a signal (4-20 mA) back to the PLC. This signal at the PLC allows operators to monitor usage throughout the process.

Advantages of Using GPI Flow Meters:

• Cost Savings
• Safety
• Compact Size
• Accuracy
• Easy to Install

Market: Pharmaceuticals

Application Category: Batching

GPI Flow Meters Used: GNT-051 with GX500

Problem:

The manufacturing process required accurate measurement of two materials into a single batch. Two lines supply materials that are batched into a blend tank.

Flow Meter Application:

The manufacturing process required an accurate measure of two different fluids into a day tank.  The blended materials, acrylamide (ACR) and glycerine (GLY) are then used in a subsequent process. Accuracy of measurement (+/-0.5%) was a critical requirement of the process and provided a cost savings.

Flow Meter Drawing:

Solution:

G Series Meters added to the individual lines send a signal (4-20 mA) back to the PLC. This signal at the PLC allows operators to monitor usage throughout the process.

Advantages of Using GPI Flow Meters:

• Cost Savings
• Self Contained
• Compact Size
• Accuracy

Market: Food

Application Category: Batching/Dispensing

GPI Flow Meters Used: G2S07N09GMA

Problem:

Portable cleaning solution carts need to be loaded with caustic and acidic cleaning agents. These agents vary in density and pH. Both batch and
continuous total are required when loading the carts with solutions.

Flow Meter Application:

Portable cleaning solution carts are used to sterilize equipment and process rooms. These carts are loaded with caustic and acidic cleaning agents from large tanks or totes. The cleaning agents vary in density and pH so material compatibility is important. The G2S07N09GMA fits the application and provided a cost savings for the end user. The G2 meter is easy to calibrate to changing ingredients and is simple for the operator to use.

Flow Meter Drawing:

Solution:

Choosing the G2 series meter allowed us to monitor batch and continuous totals during batching. The GPI meter is compatible with the variety of cleaning agents used in this process.

Advantages of Using GPI Flow Meters:

• Cost Savings
• Self Contained
• Compact Size
• Digital Readout
• Material Compatibility
• Upgrade in Technology

Market: Water Supply/Irrigation

Application Category: Monitoring

GPI Flow Meters Used: G2S10N09GMA

Problem:

Homeowners and businesses need to verify flowrate of water supply and accuracy of city equipment from main water line to individual properties. Other methods of verification can be inconvenient,time consuming and costly.

Flow Meter Application:

Use this compact meter to verify/test the water flowrate from the city main to individual homes or businesses. Use the GPI meter in the test assembly (shown below) to perform two tests.

1. Install the G2 meter on the supply line of the city main to verify flowrate to the residence. Open valve and check flowrate.
2. Install the residential meter on the downstream of the testing assembly to verify proper functioning of residential meter.

These two tests allow troubleshooting to be done on-site, saving labor time and money. Field crews are able to isolate water main problems and identify residential meter malfunctions.

Drawing of Application:

Solution:

Remove the residential meter from the line. Install either a G2S10 or G2S20 meter to the residential service line. Check flowrate. A secondary test
is done by installing the residential meter on the downstream side of testing assembly. Check and compare accuracy.

Advantages of Using GPI Flow Meters:

• Cost Savings
• Compact Design
• Accurate
• Digital Readout
• Reliable

Market: Food, Beverage, Tobacco

Application Category: Batching

GPI Flow Meters Used: GSCPS-150; GSCPS-100

Problem:

Accurately measure fluid into containers at a reasonable cost while maintaining 3A sanitary requirements with a meter that can withstand repeated stop/start batching flows.

Flow Meter Application:

Manufactures using filling machines require accurate batch sizes to maintain quality control while filling various size containers. When installed inline immediately before the filling head, the GPI turbine meters fluid flow with high K-factors giving exceptional signal resolution.The pulse count is sent to a controller that counts the pulses signaling the shut off valve to open or close as required. For most food applications, the 3A sanitary meter is required. The single post rotor design allows for repeated start/stop batching flows without damaging the meter.

Drawing of Application:

Solution:

GPI turbine meters measure at 0.5% of reading accuracy and are more cost effective than weight scales or other metering devices. These meters incorporates a single post rotor design for durability and meets 3A sanitary guidelines.

Advantages of Using GPI Flow Meters:

• 3A Sanitary Approval
• Accuracy
• Cost Savings

Market: Fabrication Metal Products

Application Category: Monitoring

GPI Flow Meters Used: A109GMN100NA1 113265-1 Remote Kit

Problem:

Companies need to adjust flowrate to maintain a constant temperature of cooling water used for various processes. Unstable or fluctuating chill water temperatures can cause quality problems or possibly even damage to expensive equipment.

Flow Meter Application:

In the water chiller/cooling tower process there are multiple variables related to the Btu extracted from the incoming water. Those variables include Thermal Capacity, Air Flow Rate, Air and Water Contact Time and Circulating Water Rate. Two of these variables require a flow meter to accurately predict the efficiency of the cooler. Flow meters are required on the makeup water line and on the Circulating Water line in order to maintain the most efficient balance of recirculated water and makeup water to air flow. A flow meter is placed on the Circulating Water line to monitor flow rate. In some applications a second meter is placed on the makeup water line to monitor amount.

Drawing of Application:

Solution:

Add a flowmeter in line to monitor the flowrate through the chiller.

Advantages of Using GPI Flow Meters:

• Battery operated
• Compact Design
• NEMA 4 Enclosure
• Accurate
• Not dependent on mounting orientation
• Display can be mounted remotely
• Nylon housing is compatible with raw water

Market: Stone/Clay/Cement

Application Category: Monitoring

GPI Flow Meters Used: 01N31GM and A109GMN100NA1

Problem:

Drivers need to add water on site to bring the mix to suitable slump rating. The amount of add water is very subjective and is not monitored. This results in variances in batches and quality of product.

Flow Meter Application:

Monitor the water added to the cement batch in the mixing truck after it has left the batch plant. Several state Departments of Transportation require that if a truck will be used in DOT contract work, it will be equipped with a meter and any water added to the mix will be logged. The strength of concrete is dependent, to a large degree, on the amount of water used in the mix. All DOT and most other contracts specify the “Slump” or stiffness of the mix along with a list of other attributes. Redi-mix plants maintain very specific recipes for the different grades of concrete. When excess water is added in the field, the quality of concrete is compromised. It is very important that the redi-mix company and the customer can verify that any specific batch falls within the tolerances of the original recipe. Place the meter in-line on the truck between the water storage tank and the mixing drum. Valves are arranged so that any water added to the mixing drum will be metered. Note: Remote display option requires A1 meter choice.
