Bottling

Litre Meter specialise in the design, manufacture and supply of flowmeters. The unique Pelton wheel based meter design ensures an inherent reliability which has been proven in more than three decades of operation. Listed below are all the flow meters within our range that are suitable for bottling:

Pelton Wheel Also known as a radial turbine the highly efficient Pelton Wheel meter has some major advantages. The very large blade area compared with the flow inlet port size produces an exceptionally wide range flowmeter which can measure very low flows. The flow through the inlet of the meter is accurately directed onto the rotor which rotates at a speed in linear proportion to the flow rate. A small sensing coil detects the ferrites mounted in the flow meter rotor blade tips as they pass. No drag is imposed on the rotor which assists in the measurement of extremely low flows. Sapphire bearings provide a very low friction mechanically-robust bearing with long life characteristics. Turndown can be as high as 280:1. Ideally suited for low viscosity process liquids measurement up to 2" pipe sizes and larger and up to 10cSt. 0.003 to 500 l/min; ±2.0% of reading (also 1.0%); they provide a high frequency output which is ideal for batching. Acceleration at start of batch is matched by the light weight of the Pelton Wheel rotor. Once the flow has stopped the rotor continues to spin down for a short amount of time. The input from the flowmeter should be inhibited at the end of batch signal. For fast batching Litre Meter recommend running the flowmeter constantly and diverting the fluid into the batch and out again. In this way there are no acceleration or deceleration issues and batch time can be reduced to less than 3 seconds. Repeatability +/- 0.2%.
Electromagnetic Magnetic flowmeters, also known as electromagnetic flowmeters or induction flowmeters, obtain the flow velocity by measuring the changes of induced voltage of the conductive fluid passing across a controlled magnetic field. The fluid has to be conductive so tap water and waste water are OK. Care has to be taken in measuring solvents, hydrocarbons, de-ionised and demineralised water where electromagnetic flow meters are not normally used due to low conductivity. Contact Litre Meter for full details. 3mm to 2000mm although insertion units can be used up to 3000mm. ±0.2% over flow range 0.5 to 5 m/s; turndown 1000:1; maximum velocity 10 m/s. Sampling time is 10 or 20 times per second depending on converter. A high sampling time is essential for short term operation.
Helical Screw

Positive displacement flowmeters, also known as PD meters, measure volumes of fluid flowing through by counting repeatedly the filling and discharging of known fixed volumes. A typical positive displacement flowmeter comprises a chamber that obstructs the flow. Inside the chamber, a rotating/reciprocating mechanical unit is placed to create fixed-volume discrete parcels from the passing fluid. The helical screw principle uses 2 counter rotating gears to form a continuous constant volume cavity. The SRZ series is available exclusively in stainless steel.
