Master-Touch products include a rugged, cleanable, thermal mass flow sensor. These units consist of a sensor assembly which utilizes two RTD (Resistance Temperature Detector) sensing elements. The sensors consist of reference grade platinum, ceramic, glass, and also stainless steel. Two platinum resistance sensors are built up upon the ceramic substrate and then given a thin glass coating. The assembly is then slipped into a stainless-steel sheath for corrosion and abrasion resistance. The sensor assembly is large, rugged, in addition to being relatively insensitive to dirt buildup.
During operation, the temperature sensor constantly measures the ambient temperature of the gas and maintains a reference resistance on one side of a bridge circuit. The temperature sensor and bridge circuitry forces the second sensor through self-heating to a constant temperature above that of the gas stream. The bridge maintains the overheat temperature and counterbalances the temperature effects through EPI’s proprietary temperature compensation techniques.

9000MP Multipoint Flow Meter for Gas Flows
Multipoint flow meter systems measure gas flows where two or more sensing points are necessary due to large cross-sectional areas, such as large air intake ducts, air exhaust, or flue stacks.
Master-Touch 9000MP Multipoint flow meter Systems are widely in use throughout the world, providing our customers with years of steady, reliable service. In combination with EPI’s new Air Purge System, Master-Touch 9000MP multiple point flow systems are ideal to an even greater variety of industrial applications. The probe design supports applications as diverse as ambient air flows in HVAC ducts, exhaust gas in large diameter stacks, boiler NOx efficiency systems, and municipal waste incinerators.
Our customers include global companies for example, environmental/ HVAC system integrators, pulp and paper mills, power and energy companies, etc. The configuration and installation options support facility retrofits as well as the most modern new construction requirements.
Configuration of the EPI Master-Touch Thermal Mass Flowmeter
The Master-Touch 9000MP Multipoint System includes one or more 9000MP probes and a 9600MP System Control Panel. The 9000MP flow transmitter probe assembly is the heart of the system. The probe assembly typically has two or more flow sensors mounted in a 1.5″ OD probe shaft. The 9000MP probe’s sensors are removable for field replacement in case of damage. Each sensor matches to its own bridge board and microprocessor to function, in effect, as a complete flow meter. The linearized output signals from the multiple sensor assemblies in each probe average to create one overall probe output signal.
The probe’s average output signal transmits to a Master-Touch 9600MP System Control Panel (SCP). If the installation contains more than one probe, the output signals from all the probes transmit to the SCP. Then, the SCP averages the values to create one system output. The System Control Panel is housed in a 12″ x 10″ NEMA 4X fiberglass enclosure. The SCP provides the power for the probe assemblies and receives the average outputs over a four-wire cable to each probe.
It also includes its own microprocessor assembly for system-level control and flow display. The SCP provides two analog output signals (0–5 VDC and 4–20 mA), as well as RS232 & RS485 Modbus RTU communications. The 4–20 mA grand average output can drive up to 1200 ohms.
Optional Air Purge System
The optional Air Purge System (APS) provides a means of cleaning the sensors in applications where particulates cause problems. Operators can externally control the frequency and duration of the purge cycle or by using the Master-Touch software. The system can also be set to maintain the flow rate at its level when the purge is active. This important option preserves the integrity of the flow rate and elapsed total data which might otherwise be compromised by the flow of the purge gas.
Thermal mass flow meters use the principle of convective heat transfer to directly measure mass flow. EPI’s proprietary thermal mass flow sensors use two ratiometrically-matched, reference-grade platinum Resistance Temperature Detectors (RTDs). A 316 Stainless Steel sheath encapsulates the platinum sensing element wire or, if necessary, a Hastelloy C sheath.
Our microcontroller smart sensor technology preferentially heats one RTD with the other RTD acting as the temperature reference. The process gas flow dissipates heat from the first RTD, causing an increase in the power necessary to maintain a balance between the RTDs. This increase directly relates to the gas molecular rate of flow. Our sensors feature temperature compensation for a wide process gas temperature range and insensitive to pressure changes, so the output signal is a true mass flow rate signal.
