Scope of This Manual

SCOPE OF THIS MANUAL

This manual is intended to help you get the FloClean Meter up and running quickly.

MPORTANTI

Read this manual carefully before attempting any installation or operation. Keep the manual accessible for future reference.

UNPACKING AND INSPECTION

Upon opening the shipping container, visually inspect the product and applicable accessories for any physical damage such
as scratches, loose or broken parts, or any other sign of damage that may have occurred during shipment.

OTE:N If damage is found, request an inspection by the carrier’s agent within 48 hours of delivery and file a claim with the

carrier. A claim for equipment damage in transit is the sole responsibility of the purchaser.

Introduction

INTRODUCTION

The Blancett FloClean turbine flow meter is designed with wear-resistant moving parts for trouble-free operation and long
service life. The durable 316L stainless steel construction is a cost efficient flow measurement system that offers excellent
accuracy and repeatability. The FloClean turbine meter repair kit is designed for easy field service of a damaged flow meter,
rather than replacing the entire flow meter. See “Repair Kits” on page 9 for information.

OPERATING PRINCIPLE

Fluid entering the meter passes through the inlet flow straightener, which reduces its turbulent flow pattern and improves the
fluid’s velocity profile. Fluid then passes through the turbine, causing it to rotate at a speed proportional to the fluid velocity.
As each turbine blade passes through the magnetic field, the blade generates an AC voltage pulse in the pickup coil at the
base of the magnetic pickup. These pulses produce an output frequency proportional to the volumetric flow through the
meter. The output frequency represents flow rate and/or totalization of fluid passing through the turbine flow meter.

Installation

INSTALLATION

THE METER SHOULD NOT BE SUBJECTED TO TEMPERATURES ABOVE 300° F (149° C), BELOW –150° F (–101° C) OR THE
FREEZING POINT OF THE METERED LIQUID. HIGH TEMPERATURES WILL DAMAGE THE MAGNETIC PICKUP, WHILE
LOWER TEMPERATURES WILL LIMIT THE ROTATION OF THE ROTOR.

INCOMPATIBLE FLUIDS COULD DETERIORATE INTERNAL PARTS AND CAUSE THE METER TO READ INACCURATELY.

Plumbing

Install the flow meter with the flow arrow, which is etched on the exterior of the meter body, pointing in the direction of fluid
flow. Install the meter horizontally with the magnetic pickup facing upward.

The liquid being measured must be free of any large particles that may obstruct spinning of the rotor. If particles are present,
install a mesh strainer.

If small particles are present in the fluid, install a strainer upstream of the meter. See Table 1 for filtration recommendations.

Table 1: Straighter size recommendations

Severe pulsation and mechanical vibration affects accuracy and shortens the life of the meter.
Install a bypass line to accommodate inspection and repair without interrupting flow. See Figure 2. If a bypass line cannot

be used, install all control valves or restrictions that may cause the liquid to flash downstream of the flow meter. Install air
eliminators to make sure that the meter is not incorrectly measuring entrained air or gas. See Figure 3 on page 6.
