> MECHANICAL FLOW METER FOB HYDROCARBON FLOW METER SERIES 800 Body: aluminium Flow rate : from 19 to 75 l/min Accuracy : +/-1% (between 19 and 75 liters/min) Partial display: 3 digits (999 liters) Manual reset (partial display) Total display: 6 digits (999.999 liters) The joins of inlet and outlet can be configured in four horizontal and vertical positions FLOW METER SERIES 900 Body: aluminium FUEL MECHANICAL FLOW METERS OVAL GEAR MECHANICAL METER Equipco mechanical fuel meters operate by the well proven nutating disc principal. The meters are reliable, inexpensive, easy to install and simple to calibrate while having a high degree of accuracy. The large digits make reading the meter an easy task. Powered pump, hand pump or gravity FM4 is mechanical flow meter with nutating disk, designed to allow a precise measurement of Diesel oil. The nutating disk of the metering chamber, which is set in motion by the fluid Flow rate (range) 20 - 120 l/min. Meter mechanism Nutating disk Read out system: subtotal / total 4 digits (9999) / 8 digits (99999999) Operating pressure The Mechanical Flow Meter (Models 438 110 and 438 115) incorporates a three blade impeller coupled directly to a five-digit counter which records each revolution of the impeller. Please notethat the counter is non-resetting, the number of revolutions is to be read by noting the difference in beginning and end readings. Area Flow Meters The ProSense FG1 Series of mechanical variable area flow meters provides visual indication of flow rate for water or petroleum based fluids. Constructed of high-impact polysulfone plastic, these flow meters are available with 1/2", 3/4" or 1" NPT process connections and several easy to read flow scales in both gallons the flow meter and 5 pipe diameters on the downstream side of the flow meter. This helps to eliminate turbulence in the fluid. Having shorter pipe lengths, other system components and elbows to close to the flow meter may adversely affect the accuracy and repeatability of the flow meter. Piping should be the same size as the meter bore or port 8.

INTRODUCTION The need for multiphase flow measurement in the oil and gas production industry has been evident for many years. A number of such meters have been developed since the early eighties by research organizations, meter manufacturers, oil and gas production companies and others. > MECHANICAL FLOW METER FOB HYDROCARBON K33 mechanical flow meter 3 digits K44 mechanical flow meter 4 digits TECHNICAL CHARACTERISTICS : Body: aluminium Mechanism: Nylon Flow rate : from 20 to 120 l/min Partial display: 3 digits Total display : 6 digits Partial display : 4 digits Total display : 8 digits POMPES JAPY - Pare d'artivites du Moulin - B.P. 15 - 25490 FESCHES-LE-CHATEL - FRANCE Tel
