Introduction

INTRODUCTION

The Blancett Model 1200 in-line turbine flow meter was engineered for applications in highly corrosive environments. Developed for use in petrochemical and other process industries with liquid chemical flows, the Model 1200 turbine meter provides accuracy and durability in aggressive industrial environments. The meter features a 303 stainless steel body and internal wetted parts, with two type-440 stainless steel ball bearings.

OPERATING PRINCIPLE

Fluid entering the meter passes through the inlet flow conditioner, which reduces its turbulent flow pattern and improves the fluid’s velocity profile. The fluid then passes through the turbine, causing the turbine 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 (see Figure 1). 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

PRESSURE IN EXCESS OF ALLOWABLE RATING MAY CAUSE THE HOUSING TO BURST AND CAUSE SERIOUS PERSONAL INJURY.

1. Check the inside of the ow meter for any foreign material.

2. Check the turbine rotor to make sure it spins freely.

3. Check the uid lines and remove any debris.

4. Install the ow meter with the ow arrow, which is etched on the exterior of the meter body, pointing in the direction of uid ow.

5. Install the meter horizontally with the conduit adapter facing upward.

6. Thread a magnetic pickup into the conduit adapter. Tighten the pickup nger tight without forcing.

7. Secure with a lock nut if supplied.

8. Install conduit or other ttings suitable for the installation area onto the conduit adapter hub on the ow meter.

All Blancett Model 1200 turbine meters use stainless steel construction materials. Make sure that the operating fluid is compatible with these materials. Incompatible fluids can cause deterioration of internal components and reduce the accuracy of the meter.

The measured liquid should be free of any large particles that may inhibit rotation of the turbine blades. If particles are present, install a mesh strainer upstream before operating the flow meter. See Table 1 for strainer recommendations.

Part Number Size Strainer Mesh Clearance (in.)

B121-225 1/4 in. (6.35 mm) 60 0.0092

B121-250 1/2 in. (12.7 mm) 60 0.0092

B121-275 3/4 in. (19.05 mm) 60 0.0092

Table 1: Strainer recommendations

Install a bypass line to accommodate inspection and repair without interrupting flow. See Figure 2 on page 6. 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.

STRIKING AN EMPTY METER WITH HIGH VELOCITY FLOW STREAM CAN CAUSE DAMAGE.

Install a minimum length of 10 pipe diameters of straight pipe on the upstream side, and 5 diameters on the downstream side of the flow meter. The piping should be the same size as the meter bore or threaded port size.

Do not install the flow meter or connection cable close to electric motors, transformers, sparking devices or high voltage lines. Do not place connecting cable in the same conduit with wires that furnish power for such devices. These devices can induce false signals in the flow meter coil or cable, causing the meter to read inaccurately.

If problems arise with the flow meter, see Troubleshooting Guide on page 9. Consult the factory with additional issues.

Operational Startup

OPERATIONAL STARTUP

MAKE SURE TO SHUT OFF FLUID FLOW AND RELEASE THE PRESSURE IN THE LINE BEFORE ATTEMPTING TO INSTALL THE METER IN AN EXISTING SYSTEM.

1. After meter installation, close the isolation valves and open the bypass valve. Allow the liquid to ow through the bypass valve for sucient time to eliminate any air or gas in the ow line.

STRIKING AN EMPTY METER WITH HIGH VELOCITY FLOW STREAM CAN CAUSES DAMAGE.

2. Open the upstream isolating valve slowly to eliminate hydraulic shock while charging the meter with the liquid.

3. Open the valve to the fully open.

4. Open the downstream isolating valve to permit the meter to operate.

5. Close the bypass valve to a fully closed position.

6. Adjust the downstream valve to provide the required ow rate through the meter.

OTE:N The downstream valve may be used as a control valve.
