The electronic flow monitor from SIKA monitors liquid flows for failure to reach a specified flow rate. The VE monitor works on the calorimetric principle. It has no moving parts even flows with entrained solids can be checked. The monitor is of robust design, is uncomplicated to operate and is highly reliable. The VE monitor affords you a dependable and inexpensive way of protecting your installations and machines from expensive damage. The flow monitor screws easily and directly into the process line by means of a connecting thread. Since the measuring probe is available in two lengths it covers a wide range of pipes of various nominal diameters and wall thicknesses. In addition, the flow monitor is available in two versions: the VES compact version Here the flow sensor and the corresponding evaluation electronics form a single unit. This means that flow can be monitored directly at the point of measurement. the VEG remote reading version he flow sensor installed in the pipe is connected to the evaluation electronics by a connecting lead. The electronics unit has been designed for installation on a mounting rail. This means that several points of measurement can be monitored from a central location.

The overall performance of a MFC depends mainly on the mass flow sensor used in it. The leading performance of Sensirion MFC is based on Sensirion's unsurpassed CMOSens® sensor technology which combines a high precision sensor element with the amplification and A/D converter circuit on one single CMOS chip. The digital calibrated and temperature compensated sensor signal is converted directly on the CMOSens® chip into a signal which is used in the analog or digital controlling circuit to control the valve. This results in very high accuracy, fast settling time and large dynamic range. CMOsens® mass flow controllers are highly suitable for a variety of applications like dry etching, surface coating, gas mixing, gas analysis, and many others. Digital thermal mass flow controller Teledyne Hastings Instruments Mass flow techniques provide more RELIABLE, REPEATABLE AND ACCURATE gas flow rate measurements compared to volumetric methods such as rotometers and turbine meters. Mass flow measurements use the density of the gas to translate mass flow units (kg or lbs) to units of familiar volumetric terms (liters/min). However the measurements are still mass units (we call those units STANDARD liter/min (slm)) and they do not change with temperature and pressure changes. We do this by referencing just one, specific temperature and one specific pressure (STP). 300 Series mass flow instruments have flow ranges from 0-5 sccm to 0-3,000 slm; use all metal seals, provide analog outputs, and are constructed of stainless steel. The mass flow controllers have normally closed valves. Corrosive gases, with the exception of the halogens, pressures up to 1000 psig (optional) are easily measured.
