2.7 EMR3 Electronic Register 2.7.1 The Veeder-Root EMR3 electronic register head is designed to mount on top of the meter in place of a mechanical head, receiving the meter shaft drive and converting it into electrical pulses. These pulses are processed and connected via cable to the EMR3 interconnect box (usually in the cab) which contains control and calculation functions and which interfaces with the printer (see Figure 4). Operational controls are situated on membrane keys on the register head. A general view of the EMR3 head mounted on a meter is shown in Figure 2. 2.7.2 Where interfaces with pneumatic control systems are required, an interface unit may be provided. A typical unit is shown in Figure 6. 2.7.3 Interlock functions are maintained and a ticket must be printed before the next transaction can start. 2.7.4 The software issue status of the EMR3 is displayed upon switch-on. The current issue status is C06 (product return version). 2.7.5 A Veeder Root mechanical pre-setter mechanism may be fitted. 2.7.6 Temperature compensation Temperature compensation may also be implemented using an optional temperature probe. An approved temperature correction algorithm is stored in the EMR³ for automatic correction when in the temperature correction mode. 2.7.6.1 Electronic Temperature Probe (figure 7) This is a two-wire thermistor which is used as an associated measuring instrument. It is manufactured by US Sensor Corporation and has part number USP2119. Other temperature probes may be used in place of the above thermistor provided they meet the accuracy requirements of OIML R117 paragraph 2.7.2. NOTE: PT100 type temperature probes will not operate with the EMR³ system. 3 OPERATION 3.1 Description The system allows metered delivery through the hose reel (wet-hose) or through the bulk hose (dry-hose). The direction of flow is controlled by a 2-way selective pneumatic outlet valve, which does not permit simultaneous communication between the three orifices and is equipped with a locking device to prevent changeover from one passageway to the other during a measuring operation. The dry-hose is purged by compressed air, stored in a reservoir on the vehicle. This purging is automatic once the registered quantity has been accepted and cannot be interrupted or in any way controlled manually. The pneumatic circuitry uses sealed copper pipes to the blow-down valve.

Each ticket is sequentially numbered, indicates the quantity of liquid fuel delivered in each transaction and is issued at the point of delivery. 3.2 Product return system 3.2.1 Construction A product return system, under the control of a pneumatic control box, allows changeover of product on completion of a delivery. The product is returned to the selected compartment via a dedicated pipe. 3.2.2 Operation When a trade delivery has been completed and the ticket withdrawn from the printer, the wet-hose nozzle is connected to the product transfer valve Pt (Figure 1). The product return master control switch Ms (in the control box Cb) is pulled to activate it and the compartment, to which product is to be returned, is selected using the rotary selector valve Rc. The quantity of product to be returned is preset on the meter assembly head and the nozzle is opened to commence pumping. When product return is complete, the meter preset shuts off, the hose-end nozzle is manually closed and the blow-down button is manually depressed. Compressed air from air tank AT purges product from the static return line, from Pt, through the top of the compartment for approximately 7 seconds. The switch Ms is then closed to deactivate the product return system. 3.2.3 Security features and interlocks 3.2.3.1 With Mechanical head The product return system is designed to prevent operation of the product return system with a ticket in the printer. Inserting a ticket moves a slider within the printer, which switches the pneumatic valve Ps (Figure 1). This inhibits the passage of a pneumatic signal to the product return control box Cb, thereby disabling the product return controls. 3.2.3.2 With no ticket in the printer, pulling the product return master control valve Ms activates the following functions: Mechanical only

(i) It allows the rotary valve Rc to select a compartment. (ii) It opens the product transfer valve Pt to allow product flow through the

non-return valve Nr. (iii) It allows air from the auxiliary tank At through to the blow-down valve

Bd.

3.2.3.3 When product return is complete, the printer cannot accept a ticket until the meter has been zeroed.

3.2.3.4 With Electronic head On actuation of the Product Transfer controls / Guard Bar, an air signal will be applied to a pressure switch which will actuate a closed circuit. The EMR electronic Head has a provision to print the word “PRODUCT TRANSFER on the delivery ticket the contacts provided on the head are labelled PTR and GROUND this should be wired via a pressure switch box or alternatively an electronic switch can be provided. 4 TECHNICAL DATA Technical data 50 mm system 75 mm system unit Nominal bore: 50 75 mm Maximum rate of flow*: 450 1100 litres / minute Minimum rate of flow: 150 150 litres / minute Maximum working pressure: 10 110 bar Minimum delivery : 500 500 litres Liquids measured: Paraffin; kerosene; derv; gas oil Climatic environment: -10 °C to +40 °C
