For several years Positive Displacement flow meters happen to be extensively used in truck delivery of fuel products. An extensive variety of mechanical accessories could be suited to the fuel flow meter to supply the consumer having a highly accurate calculating system. Such accessories include liquid strainer, air eliminator, batch preset register, large numeral reset totaliser, zero-start or accumulative ticket printer, flow non-return valve and mechanical batching valve.
Where a digital output is needed the flow meter could be fitted having a appropriate pulse transmitter that you can use to input to remote instrumentation. Pulse Transmitters can be found with ATEX Approval where necessary. Exd Pump Switches could be fitted within the LNC or perhaps a Pneumatic Switch Box could be suited to switch the environment supply for pneumatic batch systems.
The primary, or master, flow is commonly fairly high around 1000 to 3000 l/min in most cases requires using a 3” or 4” flowmeter. The VAF MidFlow Series provides a ductile iron positive displacement flowmeter having a nominal precision of higher than .1% of studying. The fuel flow meter is generally fitted by having an Exd Shaft Encoder which supplies a quadrature square wave pulse output. The flowmeter is both ATEX and MID Approved.
For mobile fuel dispenser additives Flowquip can provide flowmeters in the VAF selection of Positive Displacement flowmeters. For Marker Dyes along with other additives the conventional flowmeter may be the B5023. This ductile iron flowmeter covers a flow vary from 1 to 50 l/min and it is fitted having a six digit non-reset mechanical totaliser. If signal retransmission is needed there’s a choice of single or dual (quadrature) NAMUR pulse output(s). This fuel flowmeter can also be ATEX and MID Approved.
For fuel installations involving really low level additive injection the VAF Milliflow M31 piston flowmeter can offer the right solution. It’s produced in stainless and it is offered using the standard VAF options of non-reset mechanical totaliser and singe/dual NAMUR ATEX Pulse Transmitter(s). The conventional flow range is 1 to twenty l/hr however for installations involving greater viscosity products the minimum flow could be reduced
For Safe Area Installations the VAF ‘E’ Series flowmeters provide a very accurate and economical solution for fuel measurement. The flowmeter will come in ductile iron and contains a powered by batteries 7 digit LCD that will display immediate flow rate and cumulative/resettable total. Again, if retransmission is needed there’s a choice of just one NPN scaled pulse output.
For low viscosity fuel applications where budgets are tight Flowquip can provide the FT3 selection of stainless Industrial Turbine flowmeters. Available in assorted sizes to deal with flows from 1 l/min to in excess of 4000 l/min these fuel flow meters could be fitted with battery or Electricity powered displays to exhibit immediate flow rate and reset/non reset totals. Pulse and/or 4-20mA optional outputs can also be found for remote recording purposes.
