Litre Meter and KEM flowmeters


Litre Meter manufacture and distribute an enviable range of flowmeter. From the low flow robustness of the VFF positive displacement meter to the precision of the Tricor Coriolis range, Litre Meter have a solution to your tricky measurement application.  Call our engineers now to receive the best advice on meter selection and application.

LM & MM Pelton Wheel

LMX, pictured, was designed from the outset with some simple parameters.  A pressure rating of 100bar coupled with a temperature rating of 100°C. End couplings are wither ½”NPT or BSP with built-in straight lengths of pipe. As a bonus the minimum fluid temperature can be -50°C and there are just 3 wetted materials. With 316 stainless steel, PTFE and sapphire in contact with the fluid there are few applications that it can’t handle. Flow rate abilities are selected by different internal jets enabling the same size body to measure from 0.004 l/min up to 65 l/min in just a few sizes.


VFF Positive Displacement

The group of VFF meters pictured are all in the LF range which covers the LF03, LF05 and LF15.  The internal chambers are interchangeable, if required, and future developments of this design will all be based around the same size chamber.  The FlowPod instrument is our standard fit offering most customers exactly what they want. Pressure and temperature ratings range from 414bar to 1380bar and beyond with temperatures to over 100°C depending on area type.

ZHM Gear Meter

The KEM ZHM, shown in High Pressure spec with blue Xylan coated bolts, is a traditional round gear positive displacement meter ideal for hydraulics measurement being capable of wide flow turndowns and a range of materials and specifications.

Tricor Coriolis

The 3rd generation Tricor Coriolis meter is now available with DSP Digital Signal Processing electronics for the ultimate in precision, accuracy.  The standard electronics is still available for general industry use at ±0.3% of reading levels. Sizes cover the majority of applications and the plain bores make selection simple.  Where pressures head north of 300 bar the TCMH can be specified which also has unique OIML137 certification for liquid hydrogen dispensing, also MID-002.

SRZ Helical Screw and HM Turbine

The KEM SRZ Helical Screw Positive Displacement flowmeter and the KEM HM axial turbine flowmeter complete the Litre Meter and KEM range. The SRZ are especially good for high viscosity or abrasive or filled liquids where they are the natural preference to the ZHM.  Viscosity change has little effect and the largest can measure 400 l/min.

The HM turbines are the workhorse of industrial measurement with a clear line of design going back several decades. They are well suited to measuring low and medium viscosity liquids whether they are lubricating or not. They can be specified for cryogenic fluids too. A variety of end fittings and materials reflect their design flexibility.


TASI Adds ONICON to Flow Segment Group

TASI and Onicon

The TASI Group recently acquired ONICON Incorporated, a private company specializing in the design and manufacture of flow meters and energy measurement systems. ONICON addresses liquid flow, steam flow, natural gas flow, airflow, and thermal energy applications with a broad range of flow meter technologies, including electromagnetic, turbine, ultrasonic, thermal mass, vortex, Pitot tube and BTU meters. Through its own acquisitions, ONICON offers six brands including:

  • Onicon
  • Air Monitor
  • Seametrics
  • Fox Thermal
  • Greyline
  • Pulsar

Larger Segment

The ONICON acquisition is another is step in the continuing development of TASI’s premier flow and level measurement business. The combined businesses now form a substantially larger TASI Flow Segment that offers an extensive range of technology to better serve customers around the globe and extend into new markets.
”The ONICON acquisition is a strategic win for everyone,” stated TASI CEO John McKenna. ”ONICON’s diversified portfolio of flow technologies compliment TASI Flow businesses with little overlap in technology, industries and geographic regions. This acquisition positions both businesses on an aggressive growth path “

Existing TASI Flow Group:

The organization joins the TASI Flow Segment of complementary businesses which includes:

  • AW-Lake Company
  • KEM Kuppers Electromechanik GmbH
  • Litre Meter
  • SignalFire Wireless Telemetry
  • Vogtlin Instruments GmbH
  • EXACT Dispensing Systems

What happens now?

John Norris, former ONICON President and Chief Executive Officer, will serve as TASI Flow Segment President with responsibilities for overseeing the entire combined group of world-class flow businesses. He will report directly to John McKenna the TASI Group CEO.
