Blue-White A-100NV Micro Flow FVS Digital Paddlewheel Flow Sensor

Electronic Flow Verification

Are you sure the pump is actually pumping?
Empty chemical tank, clogged injection fitting, lost prime, an other problems can prevent a metering pump from actually injecting chemical – even though the pump is in good working order.

Installation Options

The Micro Flow FVS (Flow Verification Sensor) is designed to give you many installation options.

The sensor can be installed

Directly on the pumphead of a Blue-White pump (see next page).
Anywhere on the discharge side of a diaphragm pump.
Anywhere on the suction side of a peristaltic pump.

The wiring for the sensor can be connected directly to a Blue-White pump. The pump will stop pumping if the sensor detects no flow. A relay will then close allowing for remote alarm indication or initiation of a back-up injector pump.

Installation Guideline

A-100NV
Peristaltic Pump

The Micro Flow FVS can be connected directly to many Blue-White injector pumps (see table below). The sensor will verify that chemical injection has actually occurred.
The pumps sophisticated electronics continuously monitor the sensor. If chemical should fail to inject, the pump will stop and an alarm relay will close – allowing for remote alarm indication and/or initiation of a back-up injector pump. Recommended sensor mounting locations differ from diaphragm pump to peristaltic pump.

Diaphragm pump installation; the sensor should be mounted on the discharge (outlet) side of the pumphead. The sensor can be mounted directly on the pumphead or anywhere along the tubing on the discharge side of the pump.

Peristaltic pump installation; the sensor should be mounted on the suction (inlet) side of the pumphead

Pump Series| Pump Type| Pump Description| **Pump Shut Down Time*| FVS Installation Location**
---|---|---|---|---
A-100NV| Peristaltic| Variable speed| User programmable (up to 256 seconds)| Suction side of pump head
A-100NA| Peristaltic| Fixed speed timer controlled| 6 seconds| Suction side of pump head
A-100NF| Peristaltic| Fixed speed timer controlled| 6 seconds| Suction side of pump head
CD1| Diaphragm| Variable speed| User programmable (up to 20 seconds)| Discharge side of pump head
MD1| Diaphragm| Variable speed| User programmable (up to 20 seconds)| Discharge side of pump head
A1| Peristaltic| Variable speed| User programmable (up to 20 seconds)| Suction side of pump head

Pump Shut-Down Time = If chemical should fail to inject in the amount of time specified, the pump will automatically shut-down, also triggering an alarm relay.

Your flow verification sensor package includes a Foot Strainer (see diagram below). This strainer will prevent any small particles from entering and clogging the Micro Body. Diaphragm pumps will require a strainer and a check valve. The part number for the strainer that includes a check valve is C-340A. Blue-White peristaltic pumps do not require a check valve.

Temperature vs. Pressure

Temperature

Pressure and Temperature

Pressure and temperature limits are inversely proportional. At the maximum suggested pressure the temperature should approach 70°F / 21.1°C. At the maximum suggested temperature the pressure should approach zero psi. We cannot guarantee our flowmeters will not be damaged either at or below the suggested limits simply because of many factors which influence meter integrity; stress resulting from meter misalignment, damage due to excessive vibration and/or deterioration caused by contact with certain chemicals as well as direct sunlight. These situations and others tend to reduce the strength of the materials from which the meters are manufactured.

Application Note

Although meters may be suitable for other chemicals, Blue-White cannot guarantee their suitability. It is the responsibility of the user to determine the suitability of the flowmeter in their application.
