Introduction

INTRODUCTION

The Blancett Model 900 positive displacement flow meter is an economically priced, high pressure flow meter for low viscosity liquids. The Model 900 meter was designed for water flood and oil field service, but can be used wherever totalization is necessary. The meter is designed with wear-resistant parts for trouble-free operation and long service life. The meter housing is made from stainless steel. The internal parts are constructed of stainless alloys and high strength engineering polymers for chemical and abrasion resistance. Maintenance kits are available for quick and easy in-line repair.

OPERATING PRINCIPLE

The liquid enters the measuring chamber through a precision inlet insert and separates into two equal streams. The streams cause the impeller assembly to rotate at a rate directly proportional to the flow rate. Both liquid streams are then combined at the meter outlet.

Installation Instructions

INSTALLATION INSTRUCTIONS

Before installation, check the flow meter internally for foreign material, and make sure that the impeller spins freely. Purge flow lines of all debris.

Install the flow meter with the flow indication arrow, which is cast on the meter body, pointing in the correct direction of flow. Install the meter in horizontal piping with the register facing upward.

The liquid being measured must be free of any large particles that may obstruct the rotation of the impeller. If particles are present, install a mesh strainer upstream of the meter before operation. Some sand and small particles are permissible. Use a 30 × 30 mesh strainer (0.020 opening).

Install a bypass line to accommodate meter inspection and repair without interrupting flow. If a bypass line cannot be used, all control valves or restrictions that may cause the liquid to flash must be installed downstream of the flow meter. See Figure 1 and Figure 2.

OPEN VALVES SLOWLY TO MAKE SURE THAT ENTRAPPED AIR DOES NOT CAUSE METER TO ROTATE AT AN EXCESSIVE SPEED. DAMAGE CAN BE CAUSED BY STRIKING AN EMPTY METER WITH A HIGH VELOCITY FLOW OF GAS OR LIQUID.

If necessary, install air eliminators to make sure that the meter is not incorrectly measuring entrained air or gas. Do not install the flow meter close to a pump. Severe pulsation may negatively effect accuracy and the life of the flow meter.

Operational Startup

OPERATIONAL STARTUP

Follow these steps when installing and starting the meter:

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

1. After installing the meter, close the isolation valves and open the bypass valve.

2. Flow liquid through the bypass valve for a sucient amount time to eliminate any air or gas in the ow line.

DAMAGE CAN BE CAUSED BY STRIKING AN EMPTY METER WITH A HIGH VELOCITY FLOW STREAM.

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

4. Open the valve to the fully open position.

5. Open the downstream isolating/control valve to permit operation.

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

7. 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.

Consult the factory to determine if the operating liquid is compatible with materials of construction; incompatible fluids can deteriorate internal parts and cause the meter to read inaccurately

Severe pulsation and mechanical vibration affect accuracy and shorten the life of the meter

Install a strainer capable of removing particles 0.020 in. (0.50 mm) upstream of the meter
