Air Eliminators

The mechanical air and vapor eliminators remove air and vapor from metering systems. Removing the air and vapor from a metering system increases the accuracy of the meter by allowing only liquid to pass through the meter for measurement. At installation, LC mechanical air and vapor eliminators are piped to a storage tank to provide a pathway and a receptacle where the evacuated air and vapor can be deposited. After the air (or vapor) has left the metering system, mechanical air and vapor eliminators seal off the pathway to prevent liquid from entering the storage tank.

Strainers (F-Series)

Strainers help to protect meters from serious damage caused by burrs dislodged from new piping, pipe scale or foreign material. The strainer’s initial cost is good insurance against the cost of down time and replacement parts incurred from a damaged meter. A meter strainer installed on the inlet side is necessary even when a coarse strainer on the upstream side of the pump is included in the system. Strainers are not meant to be used as a system filter but as limited protection for the meter element itself. Strainer baskets are available in 20, 40, 80, 100 or 200 mesh.

It guides the operator in the daily deliveries, by means of a user friendly interface, functional keys and printer sharing functionality. TRUCK III can be easily integrated in remote tracking systems and it is equipped with a remote display functionality that lets you monitor all fleet deliveries... in real time!

Mechanical Valves (V-Series)

V-Series Mechanical Valves are designed to function with a mechanical preset to effectively shut down the flow after a predetermined amount of product is delivered. The preset allows this valve to be mechanically shut down in a single stage or in two-stages. Single stage shut downs are generally utilized with slower flow rates or with more viscous products where hydraulic shock is less of an issue. A two-stage shutdown allows for a slowing of the flow rate before the final positive shutdown, thus avoiding hydraulic shock.

Pneumatic Valves (VP-Series)

The pneumatic valves can be used to intercept hydrocarbons such as diesel, gasoline, kerosene, airplane fuel products and various solvents with the exception of special versions requested by clients for the specific use. In standby (no low flow and high flow air supply) the shutter, attached to the shaft, presses on gasket  thanks to the action of a spring preventing the “IN”-“OUT” passage. Once closed, the action of the spring is reinforced by the force due to the differential section defined by the construction diameters of the shutter and its inner guide which contributes to the “seal” of the valve.

Hydraulic Valves (HPV)

The HPV Hydraulic valve works according to three operating regimes: closed, intermediate low flow position and high flow position. The high flow position can, at worst, also coincide with the valve position completely open, but nonetheless it can be regulated to limit the capacity of the line. The high and low flow positions are regulated manually from the outside by means of needles for adjustment. The flow regulator with digital valve operating mode is made possible by a closed ring control carried out by a liter counter with an electronic contometric head. The capacity can be regulated almost constantly in all of the 0-100% range of the shutter opening. The HPV Hydraulic Valve is available also in digital version.
 

Pulse Output Device (POD)

The Pulse Output Device (POD) converts the rotary motion of the Positive Displacement Flow Meter into electronic pulses. This allows the meter to interface with Electronic Register TE550 and a wide variety of electronic monitoring devices and control equipment. The POD mounts directly to the front cover of any SAMPI/LC meter in place of the packing gland. The motion of the meter’s blocking rotor is magnetically coupled through a stainless steel wall to the electronics compartment of the POD. This eliminates the dynamic seal of the packing gland and isolates the electronics from the process fluid in the meter.

Solenoid Operated Valves

Electronic valves integrate with LectroCount Electronic Registers, providing flexible control and greater accuracy in deliveries.  These two solenoid valves provide a low-volume dwell period to eliminate hydraulic shock and improve the accuracy of a preset delivery.

Solenoid block valves provide simple on/off operation typically applied for security purposes to prevent unauthorized operation. Two-stage control valves provide system security and prevent unauthorized operation. Slow closing microprocessor controlled valve, allows for preset, net and/or gross volume, and/or price.

Back Pressure Valves and Spring Loaded Check Valves

Back Check Valves are designed to prevent reverse flow and eliminate counter advancement when PTO is engaged. These valves feature built-in pressure relief to keep the meter, downstream piping and delivery hose packed to a set pressure. Full port design assures maximum system flow rate. Spring Loaded Check Valves provide back pressure to increase air/vapor eliminator efficiency and prevent reverse flow.

Electronic Air Detector (LC Sound)

The LC Sound is an ultrasonic air sensor, available with 2”, 3”, 4” square flange. It continuously monitors the presence of air/gas in a delivery, and upon detection of gas the output relay is opened. The typical application uses the output contact to control valve, pump or can be connected to a smart device (e.g. electronic flow controller). The technology guarantees accurate deliveries with no pressure drop, both in terminal and truck installations. The LC Sound utilizes ultrasonic energy to detect the presence or absence of air/gas: high frequency sound waves are easily transmitted in the presence of liquid media, but are attenuated when gas is present. The sensor uses an ultrasonic transceiver to transmit a high frequency pulse: the signal reaches the reflector placed on the other side of the flange and then comes back to the transceiver. The signal amplitude level is proportional to the presence of liquid: if air is detected, the output relay is opened. The algorithm of the electronic controller guarantees accurate air detection in a maximum time of 50ms, and automatically compensates the ageing of components, quality of the product, and flange size without periodic maintenance or field calibration.

Differential Valves

Differential valves are spring loaded valves on the outlet side of the meter. Most Liquid Controls meter systems with a vapor eliminator also have a differential valve. Vapor eliminators and differential valves work in conjunction to stop the flow of product through the meter until the vapor is eliminated from the system. In order to do this, the vapor eliminator and the valve are piped together at installation. Differential valves are normally closed, but when the pump starts and pushes product into the system, the valve spring will give way to the flow pressure. In order to keep the valve closed when vapor is being expelled from the vapor eliminator, the vapor from the vapor eliminator is routed through the piping to the back side of the valve spring. The combined force of the expelled vapor and the strength of the spring keep the valve closed until the vapor is eliminated.

Optical Air Eliminator

The Liquid Controls Optical Air Eliminator is designed for use with LectroCount® Electronic Registers. It provides for the efficient elimination of air and vapor with virtually no moving parts and without the need for floats, guide rods, reed strips, and valve plates. An optical sensor, installed in the wall of the air eliminator, is used to monitor the liquid level. The presence or absence of liquid at the sensor level activates or deactivates a solenoid located at the top of the air eliminator. The Optical Air Eliminator requires the use of a solenoid operated valve such as the E-7 or A2848-11 supplied by Liquid Controls.

Electronic Temperature Volume Compensation (ETVC) Kit

Electronic Temperature Volume Compensation Electronically records and computes changes in product temperature. Virtually eliminates the effect of product temperature change on volume delivered. This accessory is field programmable for base temperature, coefficient of expansion or API table providing easy field calibration to customer Weights & Measures standards.

Differential Pressure Sensor

The differential pressure transducer monitors the differential pressure (pressure drop) between a point immediately upstream and a point immediately downstream of the full flow fuel monitor, water coalescer, or other device typically applied in aviation fueling systems. The maximum differential pressure observed during the fuel delivery is electronically input into the LectroCount® Electronic Register.  The highest differential pressure reached during the delivery is printed on the delivery ticket to provide a record of the maximum pressure drop. The corresponding flow rate at which this maximum differential pressure is observed is printed immediately after the differential pressure reading. This information appears on the delivery ticket in the form: DP 12.4 PSI @ 242.6 GPM
